What should I do when i have been treat badly by.....?

If you work 8 hours you are entitled to a lunch break but every four hours you are entitled to a 15 minute break so you are being mistreated. Call the Dept. of Labor for more information on your rights. if you hate the job get another one. I know it may be hard to find but not impossible, keep looking while you work.Your boss sounds like a jerk.
