You are receiving that portion of your pay that is deferred to the retirement plan so that deduction does not violate minimum wage laws. You are vested in any contributions you make to the plan so even if you leave the company before you are vested in an employer's share of the benefits you will not lose the portion you contributed to the plan.
Vested pension contributions withheld from wages are counted in total compensation. Therefore, it sounds like you are actually making a legal wage.
