About SEMCO Management, Inc.
Some companies follow trends. SEMCO Management, Inc. set them.
Since 1970, SEMCO has helped business owners across California and Arizona do more — with less paperwork, less risk, and less time lost to tasks that pull them away from growing their business. What began as a pioneering workforce solution more than 55 years ago has evolved into one of the most comprehensive employment administration services available to small and mid-sized businesses today.
What SEMCO Actually Does
When you become a SEMCO Subscriber, we take on the full scope of employment administration responsibilities for your existing workforce — under our own federal payroll and tax registrations. That means payroll processing, tax filings, compliance, benefits administration, HR support, workplace injury and illness coverage, and unemployment insurance are all handled by us.
Your employees keep doing exactly what they do. They report to you. They follow your direction. Your day-to-day operations stay the same. What changes is who carries the administrative weight behind the scenes. That is SEMCO.
The SEMCO Workforce Advantage
Every employee who joins the SEMCO Workforce gains something most small business employees never have access to — enterprise-level benefits, structured workplace protections, and a formal grievance process, all backed by our Structured Labor Framework.
The Structured Labor Framework is the foundation of how SEMCO operates. It defines the standards, protections, and benefits that every member of the SEMCO Workforce is entitled to. It is what allows us to offer group-rate health coverage, a fully administered 401(k) plan, and consistent workplace standards — across every business we serve.
This is not simply an HR policy. It is a commitment to every person who works under the SEMCO umbrella.
How SEMCO Compares to a Traditional PEO
Many business owners have heard of Professional Employer Organizations — or PEOs. At first glance, they may seem similar to SEMCO. The difference, however, is significant.
| SEMCO | Traditional PEO | |
|---|---|---|
| Administrative Employer | SEMCO — exclusively | Often shared with the client |
| Administrative Responsibility | SEMCO assumes it — client protected by Subscriber Protection Agreement | Shared — client retains significant exposure |
| Workplace Injury and Illness Coverage | Carried entirely by SEMCO | Often remains client-managed |
| Unemployment Insurance | Filed and managed by SEMCO | Often remains with the client |
| 401(k) Administration | Fully managed by SEMCO — zero burden to client | Client often still sponsors their own plan |
| Structured Labor Framework | All SEMCO Workforce members covered | Not available |
| Workforce Grievance Process | Built into the Structured Labor Framework | Client must maintain independently |
| Client Role | Subscriber — a defined workforce partner | Client or worksite employer |
With a traditional PEO, employment administration responsibilities are shared. With SEMCO, we carry them — so you do not have to.
Built for the Way Business Actually Works
Running a business means navigating an ever-changing landscape of employment law, tax requirements, and compliance obligations. Missing a deadline or overlooking a regulatory change can be costly.
SEMCO has spent more than five decades staying ahead of those changes for our clients. Our team monitors shifts in EEOC guidelines, OSHA standards, federal and state employment requirements, and payroll regulations continuously. When the rules change, we adapt. When your business grows, we scale with you.
That is the SEMCO difference — not just a service, but a proven partnership built on expertise, integrity, and more than 50 years of results.
