I was recently shocked to discover that my fellow pharmacist at work had been arrested. The charges are so out of character, that I had an extremely hard time believing it was true. She doesn't know yet that I know, but I have been considering offering to serve as a character witness for her in court. I think I could provide very convincing examples to illustrate her true character. Question is... I am not sure if she has reported it to the pharmacy supervisor or not. Is this something that is required in a retail chain? More importantly, if she hasn't told him, can I serve as a witness without telling him? Or could I get in trouble too for not reporting what I know? This is kind of the critical issue for me in deciding whether or not to get involved. Thanks for any help.
