So I’m out with Covid from my job that I’m quitting (they’re aware Saturday is my last day). So this morning I notified them that my test was positive and that I still had a fever. Apparently they met with the regional manager about me and one of them accidentally recorded the whole thing and sent it to a group chat with me on it. In the meeting they claimed they don’t believe I have Covid and that I’m lying so I don’t have to come back to work. They also made assumptions about my living situation cause I live with my father and accused me of living off him and not “growing up”. Long story short I responded in the chat saying “For the record my test is positive and I sent you a photo of the positive result”. My girlfriend’s mom is claiming I can sue for defamation. Is this true? What else can I do?
