If your position at a company was eliminated in a layoff due to COVID-19, and your job is posted for open hiring three months after you signed your separation agreement, what would you do?

With the context of financial strife a few months back, it’s surprising to have seen my role come back. I could have been furloughed, but that was not an option. My position was gone. I was terminated. I had questions that would never get answers. I did not have performance issues, and I was valuable for many years, so it was unclear why I was even in the layoff pool since the value I provided was vital to the business. I didn’t hear from anyone at the company that my role was brought back. I had to find out through a notification from a job site that it was posted! Additionally, without going into too many details, several events leading up to being laid off were sketchy. In hindsight, the company might have exploited the COVID layoff to not keep less-favored employees who brought up issues with HR in the past. I’m not sure what options I have now? What would other women in specialized leadership roles do if they were in this circumstance?
