Overtime pay, retaliation

For 22 years, I've worked at the local, family owned newspaper, and until last Friday, was the paper's Special Sections Coordinator/Real estate editor. For the first 20 years, I was salaried, working in the advertising dept. and building up to my current position. Jan. 01,06 I was made hourly but still working in the advertising dept., but took on two new duties (ad scheduling and paper layout). The Adv. Manager said I could not be paid overtime, but could take off 'comp' time. This went on until 2 weeks ago when our head accountant found out I wasn't being paid overtime. HR then arranged for me to receive three past weeks (about 14 hours worth) of overtime pay. Then I learned three other employees in my department were paid overtime. On Friday, 6/15, 6 employees -- including myself and the three employees I referred to above -- were 'reassigned' in a 'companywide' restructuring. Five of the employees will be learning jobs I already know, and I have been assigned to nights and an entry-level position.
To make matters whorse, I filed for bankrupcy last year and need every cent I can get. I'm out of bankruptcy now and doing OK, but I'm 52 and jobs in my field are getting less and less everyday.
What can I do, if anything?
