A waiver of subrogation in workers comp is an endorsement where your workers compensation insurer agrees not to seek reimbursement from a third party — usually a client or general contractor — after paying a claim on your employee’s injury. It’s most often required in construction and commercial contracts, and it’s added to your policy as an endorsement, typically for an additional premium. Without it, your insurer could pursue the third party to recover what it paid; with it, that party is protected.

This guide focuses on the waiver specifically in the workers comp context — when you need it, how it works, and what it costs. For the general meaning of the term, see our explainer on what waiver of subrogation means.

How It Works in Workers Comp

When your workers comp insurer pays a claim for an injured employee, it normally has the right to recover those costs from any third party whose negligence contributed to the injury — that’s subrogation. A waiver of subrogation gives up that right against a specific party named in (or covered by) the endorsement.

Example: Your employee is injured while working at a general contractor’s site. Your workers comp insurer pays the claim. Normally it could investigate and try to recover from the GC if the GC was at fault. If your policy includes a waiver of subrogation naming that GC, your insurer agrees up front not to pursue them — which is exactly why the GC required the waiver before letting you on site.

For how this differs from a certificate of insurance, see our comparison of COI vs. waiver of subrogation.

When You Need One

You’ll typically need a workers comp waiver of subrogation when a contract requires it. That’s common with:

• General contractors hiring subcontractors
• Commercial property owners and managers
• Large clients and vendors with strict insurance requirements
• Government or institutional contracts

If a contract requires the waiver and you can’t provide it, you may be unable to take the job — so it’s worth confirming the requirement early. Our overview of why waivers of subrogation matter covers the broader rationale.

Blanket vs. Scheduled Waivers

• Blanket waiver — Applies automatically to any party you’re contractually required to waive against. Convenient if you sign many contracts, but usually costs more.
• Scheduled waiver — Names specific parties only. Narrower, and sometimes cheaper if you only need it for one or two clients.

What Does It Cost?

A workers comp waiver of subrogation is usually added as an endorsement for an additional premium — commonly a small percentage of your workers comp premium. The exact cost depends on your carrier, your state, and whether the waiver is blanket or scheduled. Because it removes the insurer’s ability to recover losses, carriers price it in.

How to Add a Waiver of Subrogation to Your Workers Comp Policy

• Confirm the contract requires it and for which coverage
• Decide whether you need a blanket or scheduled waiver
• Contact your broker or carrier to add the endorsement
• Request an updated certificate of insurance that references the waiver
• Send the COI with the waiver noted to the requesting party

When you choose between a PEO and an HRO, the core difference is co-employment: a PEO becomes a co-employer that shares legal employer responsibilities (payroll taxes, benefits, workers comp), while an HRO (HR Outsourcing) manages HR functions for you without entering a co-employment relationship. A PEO bundles HR, payroll, benefits, and insurance under one pooled arrangement; an HRO lets you outsource specific HR tasks while you remain the sole employer of record.

Both reduce HR burden, but they fit different stages and priorities. This guide breaks down how each model works, the trade-offs, and how to decide which one matches your business.

What Is a PEO?

A Professional Employer Organization (PEO) enters a co-employment relationship with your business. You keep control of day-to-day operations, while the PEO becomes the employer of record for payroll taxes, benefits administration, and workers compensation. That structure lets the PEO pool your employees with thousands of others to access group rates.

If you want the fundamentals first, our explainer on what PEO means in workers comp and our overview of 7 key PEO benefits every employer should know are good starting points.

What Is an HRO?

HR Outsourcing (HRO) means hiring an external provider to handle some or all of your HR functions — payroll processing, benefits administration, compliance, recruiting — without becoming a co-employer. You remain the sole legal employer. HRO is typically modular: you outsource the pieces you want and keep the rest in-house.

PEO vs. HRO: The Key Differences

• Employment relationship — PEO is co-employment; HRO is not. With an HRO, you stay the only employer of record.
• Liability — A PEO shares certain employer liabilities; an HRO advises and administers but leaves liability with you.
• Insurance and benefits — A PEO offers pooled workers comp and group benefits under its master policies; an HRO helps you manage your own.
• Flexibility — HRO is more modular and customizable; a PEO is a more bundled, all-in arrangement.
• Pricing — PEOs often charge per-employee-per-month or a percentage of payroll; HROs vary by the services selected.

Pros and Cons of a PEO

Advantages

• Pooled workers comp and group benefits, often at lower rates
• Shared compliance responsibility
• One bundled relationship for payroll, HR, benefits, and insurance
• Strong fit for small businesses without an internal HR team

Trade-offs

• Co-employment means sharing control of certain employer functions
• Less modular than HRO
• Pricing depends on headcount and claims history — see the 5 factors that impact your PEO cost per employee

Pros and Cons of an HRO

Advantages

• You stay the sole employer of record
• Modular — outsource only what you need
• Often a good fit for larger companies with existing HR infrastructure

Trade-offs

• No pooled insurance or group-rate workers comp
• Liability and compliance risk stay with you
• Benefits buying power is usually weaker than a PEO’s

How to Choose Between a PEO and an HRO

The right model depends on size, internal HR capacity, and how much you value pooled insurance.

• Choose a PEO if you’re a small or growing business, lack an internal HR team, and want pooled workers comp and group benefits under one roof.
• Choose an HRO if you have existing HR infrastructure, want to keep full employer control, and prefer to outsource specific functions selectively.

It’s also worth comparing the PEO model against an Employer of Record arrangement — our breakdown of PEO vs. EOR covers a related decision. For the broader case for outsourcing, see 10 key advantages of outsourcing HR.

Frequently Asked Questions

What is the main difference between a PEO and an HRO?

A PEO is a co-employer that shares legal employer responsibilities and offers pooled benefits and workers comp. An HRO manages HR functions for you without co-employment, leaving you as the sole employer of record.

Is a PEO or HRO better for a small business?

Small businesses without an internal HR team often benefit more from a PEO because of pooled workers comp, group benefits, and shared compliance. Larger companies with existing HR infrastructure may prefer the flexibility of an HRO.

Does an HRO provide workers compensation?

An HRO can help you administer your own workers comp, but it does not provide pooled, group-rate coverage the way a PEO does, since there is no co-employment relationship.

Can you switch from an HRO to a PEO?

Yes. Businesses commonly move to a PEO as they grow and want bundled insurance and benefits. A structured transition plan helps ensure payroll and coverage continuity.

The Bottom Line

PEO and HRO both lighten the HR load, but they solve different problems. A PEO bundles everything through co-employment with pooled insurance — ideal for smaller businesses that want one partner. An HRO keeps you in full control and lets you outsource selectively — better for companies with established HR. Match the model to your size, your HR capacity, and how much pooled buying power matters to you.
