I thought you qualified for Medicare regardless of how long you worked at a particular job, as the funds for your government sponsored retirement benefits are being taken out as part of your payroll taxes.

However, a spouse must be married to the retiree for no less than 10 years to be eligible to participate in the working spouse's Medicare coverage.

I have never heard of having to work at the same employer for 10 years to qualify for Medicare benefits you have already been taxed on!
