What should Human Resources do in manufacturing companies?

The truth is, nobody has the perfect formula.If someone knew exactly what HR should do in manufacturing companies, there would be no problems with turnover, production failures, or operational stoppages. In the end, it’s like any other area: we do the best we can with what we have. Some companies have figured out practices that work depending on their location, type of operation, or culture… and others, not so much.

At InterHuman, we have designed an operational Human Resources plan that has consistently delivered results in manufacturing plants. It works because we can dedicate 100% of our efforts to workforce management, while the client focuses on what they do best: producing.

Our plan is made up of 10 key areas, focused exclusively on operational manufacturing staff. I’m sharing them so each company can use them as inspiration to design their own strategy:

In manufacturing, there are no magic recipes—but there are proven systems. This plan has helped us bring stability and peace of mind to the plants that trust us.
