Food processors are doubling down on their investments in automation and robotisation in reaction to rising labour shortages. While companies queue up to get new equipment, there is still an opportunity for new job creation

Stay up to date with all of ING’s latest economic and financial analysis.

In 2021, employment in US food and beverage manufacturers grew to more than 1.93 million people, reaching a new record high. Since the huge rise in unemployment in April 2020 due to the Covid-19 pandemic, the US labour market has been experiencing a strong recovery that has left many sectors and companies struggling to fill vacancies and retain employees. In non-durable manufacturing, which includes food and beverage manufacturing, the number of job openings is more than twice as high as before the pandemic, and people are switching jobs more often.

Apart from raising wages and introducing initiatives to improve other employee benefits, companies are also turning towards automation and robotisation to keep up with consumer demand. Payback times for investments have shortened compared to the pre-Covid era as labour costs have gone up and technology has improved further. A general increase in operating profits in food manufacturing over the last two years has given many companies more space in financial terms. As more and more food manufacturers turn to automation, companies face increased waiting times for equipment due to full order books at suppliers. As a result, the implementation of automation projects will be spread out over time, meaning labour constraints will prove sticky for the time being.

The tight labour market has helped to make automation and robotisation a key topic for food and beverage manufacturers. Labour costs and the general availability of labour are, in our view, one of the three structural drivers for robotisation (read here to find out the other two). US food manufacturers made sizeable investments in robotics in 2020 and the number of new robot installations reached its second-highest level in history. This indicates that companies were able to pursue such investments in a situation with severe pressure on food supply chains and the temporary closure of some facilities due to Covid infections.

Growth in robot numbers and employment can go hand-in-hand. Employment in US food and beverage manufacturing has been growing at a steady rate. While employment decreased in 2020 due to the Covid pandemic, the rebound in 2021 was strong. Within food manufacturing, most of the work is staged around the production line and roughly one in two employees fulfils a production job. As robots are mainly employed to perform tasks along the production line, one would expect production jobs to be most affected by the increase in robot numbers. Yet, the number of jobs in production occupations has grown by approximately 15,000 between 2015 and 2021.

However, a closer look at the data shows a downward trend in the share of production jobs within total employment. While this is happening at a slow rate, production work is losing out compared to other jobs. Gradually the nature of the production work in food manufacturing is evolving from, for example, picking cookies by hand and putting them in a box, to supervising a robot that does that work automatically. So besides attracting people to keep production lines running in the short term, for food makers it’s also about training or hiring people with a more technical skillset to enable automation.

If robot numbers grow, how can the number of jobs also increase? In our view, there are five main reasons:

While automation, and robotics in particular, get a lot of attention in US food manufacturing, the future of food production very much lies in the hands of both people and machine. Human capital remains a very important asset because there are still many tasks where robots can’t match a human. Furthermore, running an automated production line still requires human supervision. So while food manufacturers have their eyes set on automation to solve some of their challenges, investing in their labour force continues to be an integral part of the solution.  

Besides their contribution to productivity, robots can also reduce repetitive and dangerous work in production processes, enhance workplace safety, and create a safe culture within companies. Improvement in employee wellbeing, less absenteeism, and fewer accidents can strengthen the financial results of operations by reducing incident-related costs, thereby leading to sustainable long-term value creation.

Sustainable reporting frameworks and environmental, social and corporate governance (ESG) rating agencies have identified employee health and safety as a material issue for food manufacturers. The Sustainability Accounting Standards Board and the Global Reporting Initiative have also released detailed standards on how to disclose information related to workplace health and safety.

Under such a context, food companies like Tyson and Cargill have started voluntarily reporting on metrics such as the reportable injury frequency rate and serious injury and fatality rate. Tyson has also set up annual goals to reduce accident recordables by 10% year-on-year.

The US Securities and Exchange Commission’s newly-released draft rules on climate-related data disclosure for listed companies will accelerate this momentum. Eventually, although not a decisive factor, food manufacturers that not only disclose but also better handle workplace safety issues could receive higher ESG scores, and robots are here to help. Improved ESG scores could then add to higher investor and consumer confidence. Conversely, major incidents at workplaces can lead to financial losses and reputational damages.
