I need help and two of us feel cheated and afraid we will lose our jobs

I and my partner have been working for a company... I'll with hold for now cause i dont want to lose my job. I have worked for them for a little over a year and my partner over a year and a half. I worked off the books for 11months for what they said insurance purposes. Now on the books.. we both have requested pay stubs or something and i have been told "we dont do that here" I cant show any proof of income or what i make my checks never seem right i was told a month ago I got a raise thought I was being paid 12hr but my check came last week it was low so i called and was told well I had no idea two weeks before that i got a check and it wasn't signed by my employer so not even my bank would cash it.... my partner is about to lose his house because he can't show proof of income to the bank.. he makes 15hr i supposedly got my raise again starting this past monday.... I got 58 and a half hours this week no idea what's being taken out seems like to me i worked for less made more elswhere
