Re:Very Astute of you- but then

no one promised you cutting edge legal advice by posting on CZ

I did not see you quandry

But if something is going on that is untoward at your workplace then
1. you must be able to prove it(no closed doors and suspicions)
2. If you have collaborative proof , and you feel the supervisor will not or is involved in some fashion

Contact the Department of Labor- or go to the website

Find the statutes that apply to the wrongoing

Write them a letter (have patience) and then take your letter
to your HR department or to an employment law attorney

which ever you feel more comfortable with Tweet
