Organizing the supply chain: interview with Jeff Farmer
There are a lot of folks working in transport and logistics who are unaffiliated with a labor union. Jeff Farmer, the Teamsters' director of organizing, wants to change that.
Mark Solomon joined DC VELOCITY as senior editor in August 2008, and was promoted to his current position on January 1, 2015. He has spent more than 30 years in the transportation, logistics and supply chain management fields as a journalist and public relations professional. From 1989 to 1994, he worked in Washington as a reporter for the Journal of Commerce, covering the aviation and trucking industries, the Department of Transportation, Congress and the U.S. Supreme Court. Prior to that, he worked for Traffic World for seven years in a similar role. From 1994 to 2008, Mr. Solomon ran Media-Based Solutions, a public relations firm based in Atlanta. He graduated in 1978 with a B.A. in journalism from The American University in Washington, D.C.
The supply chain is a big and small place. Big in that it touches virtually every part of the planet and affects each one of us. But small in that the people who make it go are often one- or two-person bands that don't get much notice yet are vital cogs in an enormous wheel.
For the Teamsters union, this collection of port drivers, warehousemen and women, and loaders and unloaders, among others, offers tremendous opportunity to bulk up its membership rolls. It is uncharted territory, however, and one that's difficult to crack because of labor laws that bar independent contractors, which many of these workers happen to be, from forming a union.
The union's director of organizing, Jeff Farmer, recently spoke with Mark B. Solomon, DC Velocity's executive editor-news, about the problems facing workers who feel they have no voice, how the Teamsters want to move the needle on the all-important issue of worker classification, and the supply chain becoming the union's top organizing priority.
Q: What is your message to persuade workers who have never been unionized and may never have thought about the value of union representation?
A: We listen to what workers say about their work. Their primary concerns are not about wages and benefits. Their issues are with how they are treated, their employer's lack of respect for them, unilateral changes imposed on them, and general unfairness in the workplace. Simply put, their voices are not being heard. Our message is simple: To have a real voice on the job, workers need to stand together, form their union, and win the right to sit across from their employer and bargain collectively. The only way workers can have effective input on the issues that affect their work lives is to win the right to bargain a union contract—which guarantees those wages, benefits, and conditions.
Most workers intuitively understand that with strong Teamster representation backing them, they can win improvements. We also know from research that, if given a free choice, a huge percentage of workers would choose union representation. Nevertheless, workers face real fear in exercising their rights: fear of retaliation from their boss, weak labor law protections, and the widespread use of union-busters. Our job is to give workers hope, confidence, and a plan to successfully fight back, to demonstrate that it can be done.
Q: The growth of e-commerce fulfillment has created job security for warehouse labor that has seen wages rise in the past two years at a faster rate than virtually any other U.S. occupation. How do you convince these workers, who finally have bargaining leverage given the industry's dynamics, that union representation is an asset?
A: This has not been our experience. If anything, there is less job security, less worker power in this industry. The e-commerce giants have incredibly high turnover with a relatively small permanent employee workforce, and they rely heavily on temporary help. Most of the workers who move the goods through these facilities are employed by third-party agencies and have no job security, few if any benefits, and absolutely no power. Also, much of the work is increasingly automated, displacing even more workers. These trends are being copied across the logistics industry by large and small players. We see it at most warehouses where we have been organizing. All of this poses enormous challenges for workers to organize.
Q: How do you figure out the logistics of organizing workers who are so dispersed, where you might have four workers at this location, five workers at that location, and so on?
A: This is what we do, what the job of organizing is. Our model relies on one-on-one conversations with workers and their families outside of their workplace, in addition to on the job. It is hard, but we have tools to help us figure out the logistics and track our progress. It has always been boots on the ground, with one-on-one communication to organize workers. In that regard, our current Teamster members—those working in the same industry as the workers we're trying to reach—can be the most effective advocates in describing the rights and benefits they have gained.
Q: What is the biggest challenge you expect to face as you expand your organizing efforts into areas that have been largely foreign to the Teamsters?
A: There are not too many areas foreign to the Teamsters. We pride ourselves on being one of the most diverse labor organizations in the world, having members that range from airline pilots to zookeepers. However, our organizing efforts these days are focused primarily on transportation and the global supply chain. Here, we are uniquely positioned to take advantage of our existing power in freight, warehousing, package delivery, ports, and air cargo down to the last leg of the product chain in waste management and recycling.
Again, the principal obstacle faced by workers is the lack of effective protections when they organize. Labor law has not kept pace with modern corporate practices of outsourcing, the misclassification of employees as "independent contractors," and other schemes to escape liability to workers and government.
Q: There have been several court rulings in the past couple of years that transport workers once classified as independent contractors were in reality company employees. This may become a pivotal issue because labor law bars independent contractors from forming a union. What is your strategy here?
A: We have taken this issue head-on. We are leading the way to challenge management's claims about independent contractors as part of our efforts to organize port drivers and local delivery drivers. As you said, the National Labor Relations Act (NLRA) doesn't allow truly independent contractors to form a union. So if the workers are independent, we can't organize them. But the scam practice of misclassifying workers who are not independent and have no control over their work has become widespread, and workers are starting to push back.
We are coming to the aid of workers who have been misclassified. Corporate-driven efforts to mislead workers, unions, governments, and communities by misclassifying huge segments of workers as independent contractors were hatched many years ago to limit liability for companies, to divert responsibility, and to ultimately push costs onto everyone else. Through the Teamsters' efforts, more people have become aware of the misclassification issue, and its truly sham nature is being exposed.
Q: Do you have any estimate on the size of the potential market?
A: The Bureau of Labor Statistics (BLS) in its 2016 report on union membership found that only 6.4 percent of the private-sector workforce is unionized. Obviously, there are millions of workers without the benefit of a voice at work. If our nation is to truly address the alarming decline of the middle class and to deal with the problem of income inequality, we must organize workers on a massive scale, and at an accelerated pace. This may sound like a pipe dream, but as we have seen, workers are increasingly fed up. They have had enough of working harder for less, having no say on the job, and facing an insecure future with no pension or retirement—and they are looking for a way out. There is tremendous potential to organize them into unions.
Q: You have targeted XPO Logistics Inc. largely because it touches so many parts of the supply chain. It has a significant union presence in Europe through its 2015 acquisition of French firm Norbert Dentressangle. There have been worker protests at various XPO-related events. Are you taking steps to combine organizing efforts with those of XPO's European unions, and what are the cultural and workplace challenges in doing so?
A: We have a very close relationship with our brother and sister unions overseas. We work with the International Transport Workers Federation and with individual unions in countries across Europe and in other parts of the world.
XPO operates in a global economy, where business is done at different levels of union density and labor relations. It is imperative that those of us who represent workers' interests have matching global reach. We have worked with our international allies for many years. Today, our relationships are more tightly knit than ever before. European union representatives joined us last year at XPO's annual shareholder meeting, and they made it clear that we are a family of unions that stand together with a common goal of winning dignity and respect for XPO workers.
Picture a busy DC, with manually operated forklifts, people, and pallets in constant motion. At the same time, the stationary equipment they interact with, such as conveyors and palletizers, is industriously whirring away. Together, they are performing something akin to a carefully choreographed ballet.
Now add driverless forklifts to the mix. Shuttling along without a human operator on board, they may look like they’re operating independently, but they’re not. They’re actually in constant contact with other equipment and software, making sure they perform their part in the dance at the right moment. Without that ability to communicate, the forklifts—and other warehouse operations—could come to a standstill.
Who, exactly, are driverless forklifts “talking” to, what information are they sharing, and how does that exchange happen? We asked automation experts to explain. They also shared tips on ensuring successful communication between automated lift trucks and other equipment and software.
TWO-WAY COMMUNICATION
Lift trucks that do their jobs without a human operator on board cannot “speak” directly to each other. “As it stands now, there is no peer-to-peer communication or interaction on a forklift-to-forklift basis,” notes David Griffin, chief sales officer for Seegrid, a developer of autonomous lift trucks and AMRs (autonomous mobile robots). There is, however, interaction between forklifts via a centralized fleet manager system (also referred to as a traffic management system or an automation server). This “overarching conductor of the automated system” assigns tasks to each forklift, controls the route the trucks will follow, and manages traffic flow, says Nick McClurg, a sales engineer at forklift maker Hyster Co.
The forklifts communicate with many kinds of material handling equipment, such as robotic palletizers and depalletizers, stretch wrappers, conveyors, automated storage and retrieval systems (AS/RS), and dock equipment. That communication must be bidirectional, says Michael Marcum, senior director of autonomous vehicles at systems integrator Bastian Solutions, a Toyota Automated Solutions company that also makes robotic forklifts. Much of the exchange consists of messages that indicate status—whether or not the two pieces of equipment involved are ready to conduct a transaction. For example, if a forklift will be delivering a pallet to a stretch wrapper, then the wrapper has to tell that forklift, via the fleet manager system, that the load position is empty and the forklift is allowed to set a payload there, Marcum explains. After a pallet has been wrapped, the stretch wrapper will call for a pickup via the fleet manager. Once the forklift picks up the wrapped pallet, it must confirm to the stretch wrapper that it has departed; without that signal, the wrapper cannot receive its next load.
If a truck is not ready for an assigned task, it signals that status to the fleet manager, and the task will be reassigned to another nearby vehicle, says Jayce Nelson, sales manager, North America, for Kion Group’s Linde Automated Solutions, a specialist in automated forklifts and software. When the assigned forklift is ready to approach, say, the end of a conveyor to pick up a load, it uses its vision systems, such as 3D cameras, to align itself with the equipment.
With their control software, robotic forklifts also have the ability to communicate with other warehouse equipment, like fire-detection systems and automated rollup doors. “If a device is capable of sending or receiving electrical signals, then the vehicle can interact with that device via the automation host software,” McClurg says. Even a piece of mechanical equipment could be outfitted with sensors that help it interact with automated forklifts, according to Brian Markison, director of sales for Rocrich AGV Solutions, a joint venture of Mitsubishi Logisnext’s Rocla and Jungheinrich units that specializes in automated guided vehicles.
The capability to communicate with different types of devices enhances warehouse safety, Griffin says, because it enables automated forklifts to talk to safety equipment like pedestrian warning lights and intersection gates. And since the robots constantly transmit their location, the traffic control system can identify developing problems and prevent them. For example, the system will stop an autonomous forklift from entering an intersection that’s occupied by another lift truck. Once the other truck has moved on, the system will give the approaching forklift the “all clear,” he says.
Hardware isn’t the only thing driverless forklifts can talk to; they also are in continual dialogue with various types of software. “Most commercial warehouse software programs today have the capability for two-way communication, and most can be integrated with automated lift truck fleet management software,” observes John Wilkins, a sales engineer for Yale Lift Truck Technologies. The most common are warehouse management systems (WMS) and warehouse control systems (WCS); others include enterprise resource planning (ERP) software, fleet management and telematics systems, and transportation management (TMS) and order management (OMS) systems.
As for how that might work, Rocrich’s Markison gives the example of a WMS sending an order to move a pallet from one location to another. The order typically will include start and completion time, and some indication of the move’s priority. “That order can then be taken into the fleet manager, which will appropriately queue up the tasks that need to be done,” he explains. The forklift must also report completed missions back to the WMS.
HOW TO TALK TO A FORKLIFT
Communication between robotic forklifts and warehouse equipment and software happens in a number of ways. Which method is deployed depends on the equipment and software involved as well as the tasks to be carried out. Each installation is unique in some way, but there are some commonly used approaches.
Some communication protocols are more widely used than others. Examples of those in widespread use include modbus, a serial communication protocol that governs an initiating and a responding device, and CANbus (Controller Area Network), a real-time communication protocol that transmits data to networked industrial controls.
A driverless forklift’s interface with other equipment could be something electromechanical, such as a photo-eye sensor, says Jeff Kuss, product manager–automated solutions at forklift maker and intralogistics specialist The Raymond Corp. A sensor at the end of a conveyor, for instance, could detect the presence of a pallet. That triggers the sensor to create an electrical signal that it sends to a programmable logic controller (PLC). The PLC receives the electrical signal as a digital input and then transmits a message, via ethernet, to the server that controls the automated vehicles. Finally, the server sends the instructions over Wi-Fi to the closest available forklift to “pick up the pallet and take it to Location X.” (Some facilities use Bluetooth or cellular transmission instead of Wi-Fi.) Data that identify loads and trigger a task can also be acquired through IoT (internet of things) platforms, RFID (radio-frequency identification) systems, and barcode scanning.
Another option, Bastian’s Marcum says, is to use infrared-based optic couplers that share bits (binary digits, the smallest units of digital information) as inputs and outputs. When the forklift gets within a certain distance of another piece of equipment, “the two devices can talk to each other, similar to the way a TV remote works,” he explains.
Usually, though, software is a critical intermediary between driverless forklifts and other equipment. It can be complicated. In the case of a WMS, McClurg says, his company’s approach is to send a text or JavaScript Object Notation (JSON) file to the WMS; in exchange, the WMS sends a file to a folder on the localized network that can be accessed by the automation host software. The fleet manager reads the file and executes it. Once the task has been completed, a message is sent to another folder. The WMS opens it, reads it, and, based on its contents, either closes out the order or sends additional instructions.
To ensure that interfacing software programs understand the messages they receive from each other, it’s often necessary to create an application programming interface (API). An API is a comparatively simple type of middleware—or software layer—that acts as a translator, facilitating communication by reformatting messages so they will be intelligible to the receiver. In essence, they are “setting ground rules in terms of what information is passing back and forth and what it means,” Markison explains.
In some cases, more complex middleware may be needed. According to Brice Bucher, senior manager of products at software developer and systems integrator Flexware Innovation, APIs have limitations. In a presentation at the Autonomous Mobile Robotics & Logistics Conference 2024, Bucher noted that APIs don’t address data transformation, protocol conversion, or business logic integration. When each system has different data formats or requires specific protocols, middleware bridges those gaps, he said. Middleware also ensures that data moves between systems without delay, he said. For example, if an AGV completes a task, middleware can instantly trigger updates across systems, so that WMS, ERP, and other systems are aligned in real time.
CAN WE TALK?
Raymond’s Kuss notes that each communication integration will be unique in some way. That’s partly because automated forklift vendors and suppliers of fleet manager systems have proprietary interfaces. On top of that, software with some degree of customization, such as a WMS, may require modifications to the fleet manager system, he explains. What’s more, adds his colleague John Rosenberger, director, iWarehouse Gateway & Global Telematics, “even if we know the format for efficient data transfer, the content of the messages may differ depending on the forklift manufacturer, or it can be different by functionality.”
Mixed fleets with forklifts from different manufacturers present a particular challenge. Seegrid’s Griffin notes that it’s common for facilities to use robots from multiple vendors. Generally, he says, each automated solution has its own proprietary fleet manager software that understands where all units under its purview are and controls their movements. When robots of different brands cannot be confined to separate areas, it’s important that their fleet managers have the ability to communicate, so they can do things like open and close intersections where different types of robots cross paths.
While it is possible for dissimilar fleet managers to talk to each other, that’s easier said than done. “Those systems inherently are not interoperable,” Nelson says. “The need to share information like coordinates, current status, past assignments, and prioritization makes it difficult to assign travel paths.” In addition, if the forklifts are unable to communicate location information and what they are doing, that can lead to deadlock, where the vehicles simply stop—what Yale’s Wilkinson calls “the classic situation: a staring contest between two autonomous vehicles from different OEMs, neither one capable of blinking or losing.”
A solution for some facilities is third-party fleet manager software that’s designed to work in multiple brands of autonomous forklifts; examples include those offered by independent developers such as Kollmorgen, BlueBotics, Navitech Systems, and Flexware Innovation. In fact, some forklift OEMs partner with these and other providers instead of developing their own fleet managers. This opens the way for a fleet to potentially buy different robots utilizing the same control and navigation system, which will reduce complexity to some degree, Marcum says.
Communications with driverless forklifts may become simpler in the near future. VDA 5050, an open-source protocol for communication between AGVs and fleet manager systems, is currently in development. Coordinated by two German industry organizations, one for auto manufacturers and the other for material handling and intralogistics, this universal protocol promises to allow “any mobile robot, regardless of brand, [to] be seamlessly integrated into existing operations,” wrote Alfredo Pastor Tella, who runs the Europe-based AGV Network website, in a LinkedIn post. Pastor Tella wrote that Kollmorgen will introduce VDA 5050 into its robot control software in 2025, but other industry observers have noted that because the protocol’s roots are in European manufacturing and there are still technical issues to be worked out, it may be a few years before it takes hold in the forklift world. When it does, conversations with autonomous forklift fleets will likely become much less complicated to hold.
Tips for success
Want to be sure your driverless forklifts will always “get the message”? Here are some experts’ recommendations for facilitating communication with them:
Involve your IT experts early! They’ll need to identify what relevant data is currently available and where it resides. Make sure they’re comfortable that any APIs and other software meet your company’s security requirements. For cloud-based systems, verify that the vendor and systems integrator will have remote access if they need to service any of the systems or software. (Brian Markison, Rocrich AGV Solutions)
If you’re buying from different manufacturers, find out which supplier has navigation technology on the brands you’re considering and try to stay with a single system if possible. If you have a single platform, you can make a change just once and the entire fleet will receive that modification. If you have two fleet managers, segregate them as much as possible. Wherever they are separate, you’ll only have to change that one, but in shared areas, you’ll have to change both. (Michael Marcum, Bastian Solutions)
When it comes to facilitating communication, software is not always the best answer. Sometimes something simpler, like PLCs that notify equipment through very basic logic, works just fine. And it’s better to start small and integrate each function as you go, rather than try to integrate everything at once. You can tie two systems together and demonstrate the benefits from that, then use the savings to justify and help fund the next piece. (John Rosenberger, The Raymond Corp.)
Conduct testing in real-world scenarios, and make sure legacy software and communication technologies are compatible with the automation. These systems work in a dynamic environment, and a lot changes over time. Calibration tests can make sure everything still aligns correctly. And remember to inform your vendor of changes in things like throughput rates, layout, pallet sizes and configurations, products, and so on. (Jayce Nelson, Linde Automated Solutions)
In most facilities, commands and data are communicated via Wi-Fi, so connectivity and reliability are a top concern. A pre-installation survey to measure Wi-Fi signal availability and strength throughout the facility is an absolute must. Based on those findings, you may need to enhance signal strength and expand capacity and coverage. In some very large facilities, a private wireless network that uses cellular signals may be the best solution.

2024 International Foodservice Distributor Association’s (IFDA) National Championship
It’s probably safe to say that no one chooses a career in logistics for the glory. But even those accustomed to toiling in obscurity appreciate a little recognition now and then—particularly when it comes from the people they love best: their kids.
That familial love was on full display at the 2024 International Foodservice Distributor Association’s (IFDA) National Championship, which brings together foodservice distribution professionals to demonstrate their expertise in driving, warehouse operations, safety, and operational efficiency. For the eighth year, the event included a Kids Essay Contest, where children of participants were encouraged to share why they are proud of their parents or guardians and the work they do.
Prizes were handed out in three categories: 3rd–5th grade, 6th–8th grade, and 9th–12th grade. This year’s winners included Elijah Oliver (4th grade, whose parent Justin Oliver drives for Cheney Brothers) and Andrew Aylas (8th grade, whose parent Steve Aylas drives for Performance Food Group).
Top honors in the high-school category went to McKenzie Harden (12th grade, whose parent Marvin Harden drives for Performance Food Group), who wrote: “My dad has not only taught me life skills of not only, ‘what the boys can do,’ but life skills of morals, compassion, respect, and, last but not least, ‘wearing your heart on your sleeve.’”
