Do I need a lawyer?

I have filed with the Fair Employment and Housing and the federal EEOC, waiting for a reply. My employer Target put me on a corrective action and specifically defined my Family Leave in the Corrective Action. I had never had a performance issue before February 28, 2008 when my son was born with renal kidney failure and upon returning, I have had nothing but coachings, follow ups, and harassment. I expressed my concerns to the HR but he has not done anything. One of the executives quit because she refused to fire people on a target list and she is witness to this unfair/unethical work practice. I recently had another corrective and see this as a way to paper trail me out of my job. My time and my son's insurance has become too much and that is the reason. I reiterate, FMLA was stated
