Port Huron’s employer base has a shape you do not find elsewhere in Michigan.
The Blue Water Bridge makes St. Clair County one of the busiest commercial crossings on the northern border, which means a large local logistics and freight sector. Add marine and shipping trades along the St. Clair River, a manufacturing base feeding the automotive supply chain, two hospital systems, and a genuinely seasonal tourism and recreation economy, and you get a workforce with three characteristics that complicate benefits: some of it is seasonal, some of it is on the road, and some of it lives across a border.
Each of those breaks a benefits assumption that works fine in Metro Detroit. This page is about what to do instead.
CFH Insurance Consultants is an independent employee benefits brokerage. We are licensed insurance brokers and have been placing and managing group benefits for Michigan employers since 1995.
Problem 1: seasonal employees and who counts toward 50
If you have 50 or more full-time-equivalent employees the ACA employer mandate applies — and marine, tourism and recreation employers routinely miscount, because the FTE calculation aggregates part-time hours across the year rather than looking at your headcount today.
An employer with 38 year-round staff and a summer crew can cross the threshold without ever feeling like a large employer.
Two mechanisms matter here:
The seasonal worker exception. If your workforce exceeds 50 FTEs for 120 days or fewer in a calendar year, and the employees pushing you over are seasonal, you may not be an Applicable Large Employer at all. The test is specific and it is worth running properly rather than assuming either way.
The look-back measurement method. For genuinely variable hours, you measure over a defined period and then lock eligibility for a corresponding stability period. Done properly it gives both sides predictability. Done badly, or not at all, you end up reporting numbers on Form 1095-C you cannot defend.
Get this determination in writing once a year. It is the single most consequential compliance question a seasonal employer faces.
Strategic Insurance and Benefits for Port Huron Businesses
A logistics employer’s staff are not using St. Clair County providers. They are in Ohio, Indiana, Illinois, and often Ontario.
This inverts the usual network conversation. For a Port Huron manufacturer, local provider access is what matters. For a freight employer, what matters is what happens when a driver needs urgent care 400 miles from home.
Blue Cross Blue Shield of Michigan carries national reciprocity through the BlueCard program, which for a genuinely mobile workforce is often decisive. Regional plans that price well for a fixed local workforce can leave a driver paying out-of-network rates in another state.
If a meaningful share of your staff work away from home, put that question to carriers explicitly during bidding rather than discovering the answer through a claim.
Problem 3: a smaller provider market than downstate
For your local employees, the opposite constraint applies. St. Clair County has fewer facilities than Oakland or Wayne, and employees are less willing to drive to Metro Detroit for routine care.
That makes network adequacy a real question rather than a formality. McLaren Health Plan has natural leverage locally given McLaren Port Huron. Priority Health competes across the state and is worth quoting. Narrow and tiered network designs that cut real cost in Oakland County can be genuinely restrictive here, where the alternative facility is not ten minutes away.
Different parts of one workforce can need different things — which is exactly the case where modeling more than one plan option earns its keep.
Problem 4: cross-border employees
Some Port Huron employers have staff who live in Ontario, or who hold coverage on both sides of the border, or who are Canadian citizens working in Michigan.
This is not exotic here, and it is not something a standard enrollment process handles well. A few things worth knowing:
- A US group health plan generally covers the employee wherever they live; the practical question is provider access, not eligibility.
- Employees with Canadian provincial coverage may see a US plan as duplicative. It usually is not — but that conversation has to happen at enrollment, not afterwards.
- Coordination-of-benefits questions get genuinely complicated across systems. Get them answered by the carrier in writing before an employee needs the answer.
If cross-border staff are a meaningful part of your workforce, say so during bidding. Carriers differ in how well they handle it.
Plan design for this kind of employer
Level funding
For a healthy group between roughly 10 and 150 employees, level funding is usually the first alternative to model. You pay a fixed monthly amount covering expected claims, administration and stop-loss protection. If claims run under projection, a share of the surplus returns at year end. If they run high, the stop-loss layer caps exposure at a number you knew in advance.
Michigan’s small fully insured groups are community-rated on age, family composition, geography and tobacco use — not on your own claims history. A younger workforce is therefore subsidizing sicker groups in the same pool. Level funding is how that turns into money instead.
The caveat is real: an employer carrying several ongoing high-cost claims is generally better off fully insured, and that determination needs your actual census.
High-deductible plans with funded HSAs
A higher deductible paired with a real employer HSA contribution often costs less in total while leaving most employees better off in most years. The condition is that the contribution has to be meaningful and explained properly — particularly for hourly and seasonal staff, for whom a bare high-deductible plan reads as a benefit cut.
The rest of the package
Dental and vision. Inexpensive, heavily used, disproportionately visible. Often offered voluntary through payroll deduction and still well below individual pricing.
Group life and AD&D. Usually employer-paid at a flat amount or one to two times salary, issued without medical underwriting up to a guaranteed issue limit. Employer-paid coverage above $50,000 creates imputed income that runs through payroll.
Short-term disability — particularly relevant here. Michigan has no state disability program. For drivers, marine crews and trades doing physical work, off-the-job injuries are common, and workers’ compensation does not touch them. Without employer-sponsored STD, an employee who tears something on a Saturday has no wage replacement beyond banked PTO.
Accident and hospital indemnity. Voluntary, cost nothing beyond payroll deduction and setup, and pair naturally with a high-deductible plan for a physically active workforce.
Compliance checklist
- ERISA — plan document, Summary Plan Description distributed to participants, Form 5500 at 100+ participants
- ACA — at 50+ FTEs, affordable minimum-value coverage plus 1094-C and 1095-C reporting, with a written measurement method for variable-hour and seasonal staff
- COBRA — at 20+ employees, continuation coverage on a strict notice timetable; seasonal turnover generates a lot of these
- Section 125 — pre-tax deductions require an adopted cafeteria plan document
- Michigan Earned Sick Time Act — accrual and usage rules, coordinated with your eligibility tracking
What we do not do
We do not write commercial property, general liability, commercial auto, marine or workers’ compensation coverage. A freight or marine operation needs all of it, and you should have a property and casualty broker handling that side. We have no financial interest in which one.
The one place the two sides touch is disability. Workers’ comp covers work-related injury; short-term disability covers everything else. Employers who have not mapped that boundary either leave a gap or fund the same weeks twice because the disability policy was never written to coordinate with comp.
Frequently asked questions
We are seasonal. Does the ACA mandate apply to us? It depends on whether you exceed 50 FTEs for more than 120 days in the year and whether the employees pushing you over are genuinely seasonal. The test is specific — run it annually and document the result.
Our drivers are out of state constantly. Which plan is right? Prioritize national network reciprocity over local network depth. Ask each carrier directly what a driver pays for urgent care in another state, and get the answer in writing.
We have employees who live in Ontario. Is that a problem? Not usually for eligibility. It is a provider-access and coordination question, and carriers vary in how well they handle it. Raise it during bidding.
Do I have to offer health insurance? Not below 50 full-time-equivalent employees. At 50 or more, the employer mandate applies.
Do you work with employers our size? Much of our work is with employers between 10 and 150 employees, which is where plan design and carrier competition make the largest proportional difference.
