The Trade War Is Cutting His Auto-Plant Week to 3 Days. Social Security Will Count His Wages and Ignore the Check That Fills the Gap

A Michigan Assembly Line, a Shorter Week, and an Early Check

Picture a 64-year-old assembly worker at a Michigan auto plant. Tariff uncertainty is squeezing production and supplier schedules across the Michigan and Canadian auto corridor, and his employer has moved to a three-day production week. To keep him on the payroll instead of laying him off, the company enrolled the plant in Michigan’s Work Share program, which replaces part of the pay lost when an employer reduces hours. He filed for Social Security at 62 to steady the household budget. Now two very different deposits land each month: lower wages from the plant, and a Work Share check filling the gap.

He is not alone. On a retirement forum this summer, a supplier employee outside Detroit described the same setup and asked whether the state check would push him past the Social Security earnings limit. The answer surprised him, and it surprises most people who ask.

Wages Count, the Replacement Check Does Not

For anyone collecting Social Security before full retirement age (FRA), the Social Security Administration applies a retirement earnings test. In 2026, if you are under FRA all year, you can earn up to $24,480 from work before Social Security starts withholding benefits at a rate of $1 for every $2 above that line. Full retirement age is 67 for people born in 1960 or later.

Here is the part that matters for our auto worker. The earnings test counts wages from the job and excludes unemployment compensation, including partial payments from a state Work Share program. Pension income and investment income are also outside the test.

The dollars make it real.

Say his full-time pay was around $58,000, and the three-day schedule drops his wages to roughly $35,000 for the year. At that pay level, Work Share would likely provide about $212 a week, or roughly $11,000 over a full year. His cash flow would look like about $46,000, but Social Security would still see only the $35,000 in wages. That is about $10,500 over the limit, so Social Security would withhold roughly $5,260 in benefits for the year. In practice, it may hold back entire monthly checks until it reaches that amount instead of trimming every check evenly.

If the Work Share money counted as wages, that roughly $46,000 would produce about $10,760 in withholding. Keeping the state benefit outside the test protects roughly $5,500 of this year’s Social Security payments.

How the Pieces Fit Together

Two other interactions come into play. Benefits withheld under the earnings test are not simply lost. Once he reaches FRA, Social Security boosts his monthly amount to account for the months it withheld benefits. That softens the sting, though it does not undo the fact that claiming at 62 permanently shrunk his base benefit by roughly 30% compared to waiting until 67.

Taxes read the situation differently than the earnings test does. The IRS counts unemployment compensation as taxable income and folds it into the calculation that determines how much of his Social Security is subject to federal tax. So the same Work Share check Social Security ignores could still pull a bigger slice of his benefit into taxable territory at year end.

The broader labor picture provides some comfort. The national unemployment rate sits at 4.1%. This is a plant-level squeeze inside an otherwise firm labor market. Meanwhile, a mid-3% cost-of-living adjustment (COLA) is currently tracking for 2027, which will lift his monthly check regardless of what happens on the factory floor.

What to Sit With Before Adjusting Anything

The mistake hardest to undo is letting Social Security keep using an old wage estimate after the plant schedule changes. A return to full production will push his wages higher and may increase withholding; a longer slowdown will pull them lower. The Work Share checks remain outside the test either way. Reporting an accurate estimate, and updating it when the schedule changes, keeps withholding closer to reality.

One last thing worth sitting with: the earnings test only feels punitive if you assume the withheld money vanishes. In reality, the system quietly returns it later in the form of a higher benefit. A reduced work week and a Work Share check are less of an emergency than they can appear to be. Phasing out of full-time work comes with its own set of tax traps that surprise people, and we mapped four of the biggest ones in a free semi-retirement playbook. Every household’s numbers land differently, and a short conversation with someone who can look at the whole picture usually pays for itself.
