In the wake of a labor market stretched thin, the warehousing industry finds itself at a critical juncture. Despite the appearance of stability in the broader economy, a closer look reveals an alarming shortage of workers, particularly in roles that demand physical presence and repetitive tasks. As e-commerce continues its rapid expansion, warehouse operators face the daunting challenge of filling positions in an ever-shrinking labor pool. This growing gap between workforce supply and demand isn’t just a temporary setback—it’s a fundamental shift that could redefine the future of warehousing.

In Part 1 of this series, we explored the hidden challenges beneath the seemingly stable labor market—challenges that are widening the gap between workforce supply and demand. Without proactive strategies to mitigate these effects, this growing divide could severely impact business growth and innovation.

The effects of this labor shortage will vary across different industries, with some experiencing greater consequences than others. The warehousing industry, in particular, will face significant challenges due to its heavy reliance on manual labor.

Following the COVID-19 pandemic, a boom in e-commerce coupled with a dwindling labor market posed significant challenges to warehousing companies. As worker preferences shifted, jobs requiring in-person, mundane, manual work suffered the most acute shortages. The warehousing industry has a large share of such positions. Warehouse roles entail highly repetitive and physically taxing work, with little opportunity for career progression in the sector. ¹

A staggering 73% of warehouse operators report that they are unable to find enough labor, and the number of job openings in the warehouse industry has hit a record high in recent years.² 

The primary age group for workers in these roles is 18-30 years. However, in the face of a decades-long decline in birth rates and an aging population, this demographic is in short supply. Today, workers ages 18-29 make up just over 22% of the civilian labor force, down from approximately 24% a decade ago and 26% two decades ago.³

Projections of the population level and participation rate within this primary age bracket show that limitations can be anticipated in the availability of warehouse workers. As the overall population for this age group declines in the foreseeable future, concerns regarding worker availability will intensify. This is likely to be compounded by a drop in participation rates among this crucial age demographic. It can be estimated that in 2030 there will be around 1 million fewer participants in the workforce ages 18-29 than there are today (see below). ^{3, 4}

The repercussions for the warehousing industry are expected to be significant, as the shrinking pool of available workers will intensify the obstacles observed in positions that already face high turnover and supply shortages.

Amazon predicted that the company could run out of workers to hire in the U.S. by 2024 if it did not execute a series of sweeping changes, including increasing automation in its warehouses.⁵ 

Furthermore, the U.S. e-commerce market is projected to reach $8.57 trillion by 2030, representing a CAGR of 21.6% over the period 2022-2030 and maintaining high demand for workers. ⁶  This rise in e-commerce has driven a greater need for logistics services, prompting warehouse and logistics companies to require an unprecedented number of workers.

As the demand for warehousing goods and services outpaces their labor supply, warehousing companies have increased their hourly wages in an effort to attract more workers. In fact, the average warehouse worker hourly wage has increased by more than 20% in the past five years. ⁷  Despite these iterative wage increases, warehousing companies continue struggle in staffing the growing number of unfilled positions.

Furthermore, the workers that warehousing companies succeed in attracting and employing will likely be overworked and exposed to heightened safety risks. This will lead to burnout, higher absenteeism, increased turnover, and frequent errors. The lack of workers will also lead to substantial service interruptions which will drive down customer satisfaction. These unhappy customers will likely require compensation claims, further impacting warehousing company margins.

In order to mitigate the effects of these trends, warehousing companies are turning to automation to fill increasingly empty positions. Automation offers warehousing companies the opportunity to alleviate the burden of understaffed, monotonous, and physically demanding roles. Given the industry’s high turnover rates and frequent absenteeism in warehouse roles, it is unlikely that increased robotic automation will lead to significant job losses. Rather, it will offer a promising avenue for subsidizing human labor in these areas.

Automation in the Warehousing Industry

Automation is already taking shape to bridge the labor gap in the warehousing industry, with specific functions such as sorting, picking, palletization, depalletization, loading, and unloading being increasingly managed by automated systems. These tasks are ideally suited for automation due to their repetitive nature and the physical demands they place on workers. By adopting advanced robotics and machine learning, companies can ensure these functions are carried out with greater speed, accuracy, and reliability, reducing the risk of errors and accidents on the warehouse floor.

Many key players in the warehousing industry have found success implementing automation to fill gaps in the labor pool and combat the shortage of workers. Amazon, for example, has been at the forefront of this shift, utilizing robotics within its fulfillment centers since 2014. The company has now deployed over 750,000 robots globally, which not only fill vacant positions but also contribute to a safer work environment.

Recordable incident rates and lost-time incident rates were 15% and 18% lower at Amazon Robotics sites compared to its non-robotics sites in 2022.⁸

Walmart has similarly embraced automation, partnering with warehouse technology company Symbotic to implement automated solutions across each of its 42 regional distribution centers. The roles that will be subsidized by automated solutions include sorting, picking, palletization and depalletization. Although it is estimated that 1.6 million roles will be replaced following this partnership, Walmart’s VP of US Supply Chain Automation states that automation is about increasing capacity, not cutting jobs, citing that retention has significantly improved as the robots decrease the amount of physically demanding work for human workers. ⁹  

Kroger, too, is advancing its operations and subsidizing human labor with Ocado’s picking and frame loading automated solution. The solution employs a robotic arm equipped with machine vision and sensing capabilities, allowing it to pick and pack items with exceptional precision. The frame load technology automates the loading of customer orders onto delivery frames and utilizes computer vision to make real-time adjustments. ¹⁰ 

As early adopters, these companies are setting a precedent for the use of automation in warehousing, particularly in addressing workforce shortages. Their success is likely to inspire other companies to follow suit, accelerating the broader adoption of automation across the industry.

In Summary

In the face of an evolving labor market, the warehousing industry stands at a crossroads where the adoption of automation is no longer a mere option but a strategic imperative. The relentless growth of e-commerce, coupled with demographic shifts and changing worker expectations, has exposed vulnerabilities that wage increases alone cannot resolve. As companies like Amazon, Walmart, and Kroger lead the way with cutting-edge automation, they are not just filling labor gaps—they are setting a new standard for the industry. The successful integration of robotics and advanced technologies offers a sustainable path forward, enhancing both operational efficiency and worker safety. For the warehousing industry, embracing automation is not just about meeting today’s demands; it’s about future-proofing operations in a world where the dynamics of labor are rapidly shifting. Those who act now will not only navigate the current labor crunch but will also position themselves as leaders in the next era of warehousing.
