If my employer has been taking more out of my weekly paychecks than they have been forwarding to my retirement fund, could i have grounds to go after them for more than what they have actually taken from me? They have been known in the past to make so called "mistakes" on retirement funds before, and also took money out of my brothers checks for most of a year for an insurance plan that they never even set up for him in the first place. Now me and 3 of my co-workers are discovering that there are discrepancies between what we are paying into retirement and what is actually making it to our retirement funds. I have more than a couple reasons to think that there is shady business going on and i dont have any reason to believe that they arent intentionally stealing money from us. But i cant find any way to prove that they are doing it on purpose. How do i know if they are, and if they are, do we have any right to sue them for more than what we have actually lost?
