How to Structure Your HR Team as You Grow Past 50 Employees

The Problem With Reactive HR Hiring

Most companies do not plan their HR function. They hire someone when they are overwhelmed, give that person a title, and move on. Then they hit 60 or 80 employees and realize the structure does not make sense anymore. The person they hired to handle compliance and onboarding is now expected to run performance management, support managers, and oversee benefits renewal all at once. That is not a role. That is a list of problems.

Building HR intentionally takes more thought upfront, but it saves a lot of pain later.

What the Function Actually Needs at Different Stages

Around 50 employees, most companies need one solid HR generalist. This person handles the day-to-day: onboarding, employee relations, compliance, and benefits administration. They are not setting strategy yet. They are keeping the engine running.

Once you get closer to 75 to 100 employees, the generalist model starts to strain. Managers need more support. People issues get more complex. This is usually when companies benefit from adding either a dedicated HR business partner or a second generalist with a defined specialty, whether that is payroll and benefits or recruiting.

At 150 employees and beyond, you likely need someone owning the function at a higher level, an HR manager or HR director, with support underneath them.

Where Minnesota SMBs Tend to Get This Wrong

The most common mistake is hiring a senior HR leader too early and leaving them without support staff. A director-level person who is also processing payroll and handling every employee complaint is going to burn out or leave. The title has to match the actual scope of the role.

The second mistake is the opposite: keeping a single generalist in place long past the point where the company has outgrown them. That person is not set up to succeed, and the business is not getting what it needs from the function.

How to Think About the Next Hire

Before posting a role, get clear on two things. First, what is actually falling through the cracks right now. Second, what does the person in this seat need to own in 18 months, not just today. Those two answers will tell you a lot about the level and background you actually need.

If you are not sure, talking through the gap with someone who has seen a lot of HR builds at similar-sized companies can help you avoid a hire that looks right on paper but misses the point.

Getting HR structure right is one of the decisions that compounds over time. The companies that think it through early tend to have stronger cultures, lower turnover, and managers who actually feel supported.
