Wisconsin Butter Workers Authorized a Strike With Pension Contributions on the Line. Those Dollars Won’t Show Up on Social Security.

Dozens of workers at a Wisconsin butter plant have authorized a strike, putting two very different kinds of retirement money side by side. Teamsters Local 120 said workers at Foremost Farms in Reedsburg are pushing for better wages, retirement security and protections around overtime and attendance. Drew Schafer, a Foremost worker and union steward, put the retirement demand plainly: workers want pension contributions that help ensure they can retire.

For a worker in his early sixties, that sounds like one retirement fight. Social Security sees two. A bigger wage can land on his Social Security earnings record and potentially raise his future benefit. An employer pension contribution generally does not. It can strengthen the other retirement check he is building, but that contribution does not get added to the covered earnings Social Security uses to calculate benefits.

Two Retirement Checks, Built Differently

Social Security bases retirement benefits on a worker’s highest 35 years of indexed covered earnings. Wages subject to Social Security tax can strengthen that record, particularly if they replace a low-earning year or a zero. Employer contributions to a qualified pension or retirement plan generally sit outside Social Security wages. The IRS draws the line clearly: employee elective deferrals generally remain subject to Social Security and Medicare taxes, while employer matching and nonelective contributions generally do not. That creates a nuance whenever wages and retirement contributions are both in play.

Suppose a worker is effectively choosing between more hourly pay and more employer money going toward retirement. The raise can do two jobs. It raises current pay and, up to Social Security’s annual wage cap, can add to the earnings record used for his future benefit. The employer contribution supports retirement income under the plan’s rules but does not raise covered Social Security earnings. Neither is automatically the better deal. They build different pieces of retirement.

The $184,500 Line Changes the Trade-Off

There is a point where the Social Security advantage of higher wages disappears. In 2026, Social Security taxes and credits earnings only up to $184,500. A worker already at or above that amount cannot raise his Social Security record for the year with another dollar of wages. For him, shifting more compensation toward an employer-funded retirement benefit may not sacrifice additional Social Security credit.

A lower-paid worker is in a different position. If he is below the wage base and has weak years among his highest 35, additional covered wages can replace a lower year and increase the average Social Security uses to calculate his benefit. That is why two workers on the same shop floor can look at the same contract provision and have different retirement math.

A 401(k) Creates Its Own Split

The distinction gets easier to miss when the retirement benefit is a 401(k). If a worker puts part of his paycheck into a traditional or Roth 401(k), those elective deferrals generally remain Social Security wages. A traditional deferral may escape current federal income tax, but it still counts as Social Security wages.

The employer match is different. It goes into the same account and may be invested in the same funds, but it generally is not subject to Social Security tax and does not increase covered earnings. Same retirement account. Two contribution sources. Two Social Security outcomes.

Before Deciding Which Dollar Matters More

Workers do not need to reduce a contract negotiation to Social Security math, but they should know what each piece of compensation is building.

1. Check the Social Security earnings record. A worker with fewer than 35 strong covered years may get more mileage from additional wages than someone whose record is already full of high-earning years.
2. Examine the pension or retirement-plan formula. An employer contribution can be extremely valuable even though it never appears on a Social Security statement.
3. Know whether wages are already near the annual cap. Once covered earnings reach $184,500 in 2026, additional wages cannot increase that year’s Social Security record.

The workers in Reedsburg are bargaining over what retirement security should be worth. Social Security adds one silent distinction to the fight: some retirement money builds the pension, but never touches the earnings record behind the Social Security check.
