Was hired and offered a salary position never received no more than $10 a hour questioned them about contract working 50 hours without overtime pay

I later found out that other employees were not being paid for the overtime they were working..Not receiving their breaks.. Employees being hurt and company asking them to use there own insurance After bring all this to the company also the fact that they wanted me to lift heavy boxes when I have a disability that prohibits me to lift over 5lbs This the company knew before hiring me..I was fired...
