<human>: Could you distill the essence of the text into 1-3 sentences?

So I can't really get into much detail out of fear of being identified, I work for a massive international retailer and my store management is completely corrupt, forcing employees to take customer surveys and stuff along those lines. I like making money, and I like having a job. The thing is reporting it to HR NEVER works, we were confused as to why HR never investigated until a manager I know on a personal level told us that the general manager of the store has a insider that works for HR and closes the cases from his store. Our store also has one of the highest turnover rates in the territory, due to the working conditions.

I work there because they work with my college schedule and the pay isn't too bad, but I want to have an ace up my sleeve since HR isn't any help nor is the district or market manager. In fear of the event that I was terminated for doing something illegal per management would it be lawful to wear a recording device to work and record conversations with managers in hopes that a court would accept it as evidence?
<bot>: Work for a corrupted store in a big company and wanting to know if recording is legal in case I get terminated for something they told me to do. Thanks!
