I have bipolar disorder and generalized anxiety disorder and it has caused me troubles at work. I have had some absences and a leave due to a hospitalization but I have submitted paperwork from said hospitalization and a letter from my psych to prove my diagnoses. The problem is, every time I have a debilitating panic attack or episode of depression, I am taken down to a very snooty nurse in the occupational medicine department who drug tests me and places me on administrative leave. I realize that employers have a right to random drug test, but on my paperwork the nurse checks off "reasonable suspicion" even though I have come back negative each time and am otherwise a great employee. Is this discrimination? I'm feeling a little judged and criminalized and I'm wondering if I have grounds to take it up with HR. Any advice would be appreciated!
