Position eliminated then reopened after taking step down?

I was hired as a manager for a department in healthcare. I worked in this position for a few years and have been with the company for 9+ years. I’ve had meets or exceeds performance appraisals with no write ups. I did have one documented discussion due to having to leave early to help my disabled son (this was once and the documented discussion references no dates/times just that I left early). Due to this, FMLA was approved for intermittent use, but I have not needed it or used it. 2 months ago the VP and director told me there was no longer a need for a manager and my position was being eliminated. I was offered a different supervisor role (step down) with a 10% pay cut. 2 months later they secretly opened the manager position back up, did not tell me and hired a prior subordinate to the role, of a different sex, with lesser certifications/degrees than myself. I feel as if I was unfairly treated and potentially discriminated against in being told the position was eliminated to promote a less qualified individual of a different sex. I feel this may have to do with my application for FMLA. Do I have recourse?
