yes and no- if you are afraid that you are going to lose your job for filing a lawsuit then the company shouldn't be able to simply pay you a fair wage for 180 days then fire you to get away with it. On the other hand if they have been paying a fair wage for 5 years or more then you probably shouldn't be able to sue for discrimination that far back. So it's at least a place to start the discussion. Maybe each week of employment at fair pay should reduce the remaining time frame by 1 day.
