hello after getting a first and final written warning last time for something which imo was undeserved. I was told i needed to go on a cash control course and needed re training. None of which has happened. Now three out of the four shift managers are being investigated as money has gone missing. I have really had enough this time as i followed cash control procedures and i obviously have not stolen it. The manager has recently been told he faces a disciplinary as his stocks have been consistently bad since he got here three years ago. He is now finding every excuse to pass the buck and shift attention. I have not had any training off him ever and sick of him never being available to talk to. He tells me its because i only work three evenings a week but he and is favourite only do mornings. Another shift manager is feeling the same problems. Any suggestions? Could i be fired?
