Michigan's Earned Sick Time Act: Compliance Update One Year In

Quick Refresher: What ESTA Requires

The Earned Sick Time Act covers every Michigan employer, regardless of size. There is no small business exemption — Michigan's sick time law applies to every employer in the state regardless of size. Michigan joins a growing number of states requiring paid sick leave, and unlike some states that phase in requirements by employer size, Michigan went all-in from day one.

The basics:

• Accrual rate: Employees earn 1 hour of sick time for every 30 hours worked.
• Usage caps: Large employers (11 or more employees) must allow up to 72 hours per year. Small employers (10 or fewer) must allow up to 40 hours.
• Waiting period: Employers may impose a 120-day waiting period before new hires can use accrued time.
• Frontloading option: Employers can provide the full annual allotment at the start of the benefit year instead of tracking accrual.

That's the summary. Here's where it gets complicated.

Frontloading vs. Accrual: What We've Learned After Year One

This has been the single biggest decision point for employers since ESTA took effect — and a year in, clear patterns have emerged.

The case for frontloading:

Frontloading means giving employees their full allotment of sick time (72 or 40 hours, depending on your size) at the start of the benefit year. The advantage is simplicity. No tracking hours worked against hours accrued. No payroll system configurations to maintain. No disputes over whether an employee has "enough" time in their bank.

For employers with salaried workforces or consistent schedules, frontloading eliminates an entire category of administrative headaches. If your payroll team spent 2025 fielding questions about accrual balances, this is worth a hard look.

The case for accrual:

Accrual works better when you have high turnover, seasonal staffing, or a large part-time workforce. If you frontload 72 hours to an employee earning $25 per hour who quits after 90 days, you just gave away $1,800 in paid time off. With accrual, employees accumulate time proportionate to actual hours worked, which controls costs for employers with less stable workforces.

The trade-off is tracking. Your payroll system has to calculate accruals correctly for every employee, every pay period. We've seen employers discover mid-year that their payroll provider wasn't calculating ESTA accruals properly — a problem that's much easier to prevent than to fix retroactively.

The short answer: If you have a stable workforce and want clean administration, frontload. If you have high turnover or significant part-time staff, accrual likely makes more financial sense. Either way, document your method in writing and make sure your payroll system matches your policy.

The Headcount Trap: How Employer Size Actually Gets Counted

This is where we've seen the most confusion — and the most compliance risk.

Your employer size under ESTA isn't based on how many people work in your Michigan office. It's based on the total number of employees you have nationwide — full-time, part-time, temporary, and even workers provided by staffing agencies — counted across any 20 or more calendar workweeks in the current or preceding year.

Here's what that means in practice:

• Multi-location employers: If you have 8 employees in Grand Rapids and 4 in Ohio, you're a large employer under ESTA. Your Michigan employees get up to 72 hours, not 40.
• Staffing agency workers: Employees placed at your worksite through a staffing agency count toward your headcount. This catches a lot of manufacturers and warehouses off guard.
• Part-time employees: Every part-time employee counts as one employee for sizing purposes. Five full-time and six part-time workers puts you at 11, which makes you a large employer.
• Seasonal peaks: If you cross the 11-employee threshold during 20 or more weeks in a year — even if your headcount drops below 11 the rest of the year — you're classified as a large employer.

Most brokers won't tell you this, because most brokers aren't tracking it. But the difference between "small" and "large" under ESTA is the difference between 40 and 72 hours of required sick time. That's a real cost difference, and getting it wrong is a real compliance risk.

Aligning Your PTO Policy with ESTA

Many Michigan employers already had PTO policies in place before ESTA took effect. The question we hear most often: "Does our existing PTO satisfy the law?"

The answer is usually yes — with conditions.

Your PTO policy can satisfy ESTA requirements if:

• Employees accrue time at a rate at least equal to ESTA's 1-hour-per-30-hours standard (or you frontload the required minimum).
• Employees can use PTO for all ESTA-qualifying reasons, including their own illness, a family member's illness, domestic violence-related needs, and public health emergencies.
• You don't impose usage restrictions that are more limiting than what ESTA allows. For example, ESTA prohibits requiring a doctor's note for absences of three consecutive days or fewer.
• Carryover provisions meet ESTA minimums. Under accrual, employees can carry over unused time (though you can cap annual usage at 72 or 40 hours).

The biggest mistake we've seen: employers who technically offer enough PTO hours but whose written policies restrict usage in ways that conflict with ESTA. A PTO policy that only covers the employee's own illness, for example, won't satisfy ESTA's requirement to cover family member care.

This is the kind of line-by-line policy review that should be happening every year. It's also the kind of work that gets skipped when your broker is managing 500 accounts at a national firm.

Churches, Nonprofits, and the Volunteer Question

ESTA applies to churches, nonprofits, and ministries the same as any other employer. There's no religious or charitable exemption.

That said, these organizations face a specific complication: volunteers.

True volunteers — people who freely offer their time without expectation of compensation — are not employees and don't trigger ESTA obligations. But the line between "volunteer" and "employee" isn't always as clear as organizations assume.

If someone receives a regular stipend, has set hours, reports to a supervisor, and performs work that paid staff would otherwise do, they may be classified as an employee under Michigan law regardless of what the organization calls them. This is particularly relevant for churches with part-time music directors, youth leaders, or administrative staff who are paid modest amounts and considered "volunteers" by the congregation.

The test isn't what you call the role. It's the nature of the working relationship.

For part-time church and nonprofit employees who clearly qualify, the ESTA obligations are the same as for any other employer. Count them in your headcount. Track or frontload their sick time. Include them in your policy.

The Penalty Math

The financial exposure under ESTA is real and worth understanding.

For each violation, the penalty is 8 times the employee's hourly wage for each hour of sick time improperly denied or penalized. For an employee earning $20 per hour who is denied 8 hours of sick time, that's $1,280 in penalties — for a single incident.

Retaliation carries a separate $1,000 penalty per occurrence. Retaliation includes reducing hours, disciplining, or terminating an employee for using protected sick time.

With Michigan's minimum wage now at $13.73 per hour and heading to $15.00 by 2027, the per-violation penalty floor keeps rising.

For a mid-size employer with 100 employees, even a handful of violations can add up to five figures quickly. And these penalties are per employee, per violation — they don't cap out.

Your One-Year ESTA Compliance Checklist

If you do nothing else after reading this, do these five things:

1. Recount your employees. Include every location, every state, every staffing agency worker, every part-time employee. Confirm whether you're a small or large employer under ESTA.
2. Verify your payroll system. If you use accrual, confirm that your payroll provider is calculating ESTA accruals correctly. Run a sample calculation by hand and compare it to what your system shows.
3. Audit your written policy. Make sure it covers all ESTA-qualifying uses, matches your actual method (frontloading or accrual), and doesn't impose restrictions beyond what the law allows.
4. Check your documentation requirements. ESTA limits when you can require a doctor's note or other documentation. Make sure your managers know the rules.
5. Train your supervisors. Frontline managers are your biggest compliance risk. They're the ones who approve or deny time-off requests. Make sure they understand what ESTA allows and what it prohibits — especially regarding retaliation.

What's Next for Michigan Employment Law

Michigan's employment law landscape is not slowing down. The minimum wage increase to $15.00 per hour by 2027 will affect total compensation planning. A proposed Paid Family and Medical Leave Act is on Governor Whitmer's priority list — and if it passes, employers who built clean ESTA systems now will absorb the change. The ones still patching holes in their sick time policies will be starting from behind.

The Michigan Department of Labor and Economic Opportunity has signaled additional rulemaking on ESTA documentation requirements. Watch for updates from their Wage and Hour Division.

A year from now, the employers in good shape will be the ones who treated this year as the foundation — not the finish line.
