I recently quit my job of 2 yrs at Panera in Cary due to hours being reduced. This was done via text with my store gm. A few weeks after I spoke to a former co worker that said a shift manager named Josh at my former job told him that I was fired for filling up my 32oz water cups with vodka and drinking at work. I also saw another former coworker a week later and she said he told her the same thing. I tried contacting my former gm and district with no response from either. I contacted human resources and they said my gm put that I quit bc of hours on my record. I filed a complaint about the shift manager with human resources a few weeks ago and have not received any results..etc. The witnesses also have not been ?ed. The shift not is still maintaining to tell employees that for the record it wasn't put as the reason but it was. I have never been ?ed spoken to..written up..about anything much less alcohol. Do I have any case or am I wasting my time?
