My employer did not pay me for the overitme hours I have worked for him since last two years even after reminding him? what are my options?

Assuming (1) that your employer is large enough to be covered by the federal Fair Labor Standards Act, and (2) that you worked more than 40 hours in the 7 day pay period, and (3) that your job duties and pay do not exempt you from coverage by the overtime pay laws, you can notify a local employment lawyer and file suit against the employer for non-payment of overtime.  If you win the suit, the employer will be required to pay you the amount of overtime that you should have received, plus an additional amount equal to the unpaid overtime (as liquidated damages), plus your attorneys fees and costs.  You also can contact the US Department of Labor Wage Hour Division and report the employer. They sometimes will file an action for you.   Michael Caldwell 404-979-3150
