Key Takeaways
Under federal rules an employer with fifty or more full-time and full-time-equivalent employees has to offer coverage to its full-time people.
You pick a stretch of time, between three and twelve months, and you count the hours each variable-hour employee actually worked.
If an employee leaves and comes back, the question is whether they return as a new hire or pick up where they left off.
Cheboygan employers run a payroll that changes shape twice a year. County unemployment sat at 13.2 percent in March 2026 and 11.0 percent in April, then fell to 4.8 percent in June and 4.6 percent in July. That is not a soft seasonal drift. It is the same employers letting people go in the spring and hiring them back by midsummer, and it is the single fact that should shape how a benefits plan is administered here.
Most of the benefits advice written for Michigan employers assumes a stable headcount. It tells you how to compare plan designs and negotiate a renewal. Useful, but beside the point if your real problem is working out which of your people are eligible in the first place, and whether the person you rehired in May is a new employee or a continuing one.
When Headcount Swings by Season, Eligibility Gets Complicated
Under federal rules an employer with fifty or more full-time and full-time-equivalent employees has to offer coverage to its full-time people. Full-time means an average of thirty hours a week. For an employer whose staffing is flat, that calculation is close to trivial. For one whose summer headcount is double its March headcount, it is the whole job.
The rules anticipate this. Rather than testing hours month by month and moving people on and off the plan, an employer can measure hours over a defined stretch of time and then lock eligibility in for a matching stretch afterwards. It is called the look-back measurement method, and for a seasonal employer it is usually the difference between an administrable plan and a mess.
The Look-Back Measurement Method, in Plain Terms
There are three pieces, and they run in sequence.
The Measurement Period
You pick a stretch of time, between three and twelve months, and you count the hours each variable-hour employee actually worked. A northern Michigan employer with a summer peak generally wants a full twelve months, because a twelve-month window averages the busy season against the quiet one. A short window that happens to sit over July will make seasonal staff look full-time when across the year they are not.
The Administrative Period
Once the measurement period closes you need time to do the arithmetic, work out who crossed the threshold, and run an enrollment. The rules allow up to ninety days for this, and it cannot reduce or lengthen the other two periods. In practice this is where the work actually happens, and it is the piece most often underestimated.
The Stability Period
Whoever averaged thirty hours during the measurement period is treated as full-time for the stability period that follows, whatever their hours do in the meantime. The stability period has to be at least six months and at least as long as the measurement period. That is the trade: you accept that a person may be eligible during months when they are barely working, in exchange for not having to re-test anybody mid-year.
For a Cheboygan employer that trade is usually worth making. The alternative is monthly testing, which means people gaining and losing coverage on a seasonal rhythm, and an administrative burden that falls on whoever runs payroll.
Rehires, Breaks in Service, and the Thirteen-Week Rule
This is where seasonal employers most often get caught. If an employee leaves and comes back, the question is whether they return as a new hire or pick up where they left off. The general rule is thirteen weeks: if the gap in service is at least thirteen consecutive weeks, you may treat the returning employee as new. If the gap is shorter, they continue with the status they had.
The practical consequence is that a March layoff and a June rehire is roughly at the edge of that line, and which side it falls on changes the answer. An employer who assumes every returning worker is a fresh start, and applies a new waiting period each time, is very likely getting it wrong for at least some of them.
Educational organizations work to a twenty-six week standard instead, which matters for Cheboygan Area Schools and for anyone whose staff work an academic calendar. The district reports roughly 193 full-time-equivalent staff across four schools serving about 1,468 students, and a summer break is not a break in service.
Other Points for a Northern Michigan Employer
The Nearest Acute-Care Hospital Is in Petoskey
McLaren Northern Michigan operates a Cheboygan campus with a freestanding emergency department and a behavioral health center, and broke ground in June 2026 on a seventeen million dollar emergency department expansion taking it to fourteen private treatment rooms. That is a real commitment to local care. But the system acute-care hospital, with 202 beds, is in Petoskey.
When you evaluate a network here, the question is not the raw count of participating providers. It is what an inpatient admission actually looks like for your employee and their family, how far they travel, and whether the plan treats that travel as in-network. A plan that looks adequate on a statewide provider list can still be the wrong plan for a workforce an hour from the nearest inpatient bed.
An Older Workforce Changes What a Plan Is Judged On
Cheboygan County has a median age of 51.1, a population of 25,579 at the 2020 census, and is 78.8 percent rural. An employer group drawn from that population skews older than a comparable group downstate. That affects claims, and it affects which plan features people actually notice: specialist access, prescription coverage for chronic conditions, and what happens at sixty-five.
Employees approaching Medicare eligibility need to know each year whether the prescription coverage in your plan counts as creditable. Getting that notice out is a small administrative task with a real consequence attached, because an employee who goes without creditable coverage can face a permanent premium penalty they will blame on their employer.
Telehealth Is Not a Convenience Feature Here
In a county that is nearly four-fifths rural, spread across three major inland lakes and a forty-mile inland waterway, a virtual visit is often the difference between care and no care. It is worth checking what your plan actually covers rather than assuming, and worth telling employees it exists, which is the step most employers skip.
Some of Your Neighbors Are Not in the Commercial Market at All
The Coast Guard cutter Mackinaw is homeported in Cheboygan with a crew of about fifty-five. Federal employees are covered federally. It is a useful reminder when you look at local benchmarking data that the visible employers in town are not all playing the same game, and comparing your plan to theirs tells you nothing.
Who This Affects Locally
Great Lakes Tissue Company has been described by the city manager as the major industrial employer in Cheboygan, with more than one hundred employees as of early 2023, and it changed ownership twice across 2022 and 2023. Manufacturing here is essentially that plant. Beyond it, the county economic development material describes an economy resting on service industry, retail trade, and tourism.
That mix is exactly the one where measurement periods, rehire rules, and variable-hour tracking do more for an employer than any amount of plan-design tinkering.
Questions From Cheboygan Employers
We Are Under Fifty Employees. Does Any of This Apply?
The federal offer-of-coverage requirement does not. But if you do offer a plan, its own eligibility terms still have to be applied consistently, and your carrier will hold you to them. Plenty of small employers have a written waiting period they do not actually follow.
Our Headcount Only Crosses Fifty in July. Are We an Applicable Large Employer?
It depends on your average across the prior calendar year, not your peak. There is also a specific seasonal-worker exception that can apply where the only reason you exceed the threshold is seasonal staff working no more than 120 days. It is worth having someone actually run the calculation rather than assuming either way.
Can We Just Put Seasonal Staff on a Longer Waiting Period?
Waiting periods are capped, and a waiting period is not a substitute for a measurement period. They solve different problems. Using one as a workaround for the other is a common and expensive mistake.
What Should We Be Doing Before Next Season?
Fix the measurement and stability periods in writing before the next cycle starts, not during it. Decide now how you will treat rehires. Then make sure whoever runs payroll knows what the rules are, because that is where this either works or quietly does not.
