Need help

[Politicalboi]

I worked for a temp service company. They did urine drug tests but allowed you to go to the bathroom in private to take it. They assigned me a job, and while there 3 months later I had a random urine drug test by the company I was physically working at. I was working 3rd shift, and the second shift lead lady took me aside, and told me I had a random drug test. She took me in the bathroom, and told me she had to watch me urinate for the test. They had no cause to watch me. They told me it was RANDOM. Does anyone know if I have any recourse to file a suit against them. I passed the test. I have read they need cause to witness a urine drug test. And I felt violated to have to pull my pants down in front of a fellow employee. They at least should a have a nurse for that. Thanks.

Note: They did these random tests to everyone, even pre-employment for the temp service. I have witnesses.
