Just got a written warning from a meeting I had on January 6th with my 3 supervisors. I was aware I was going to get this, albeit didn't expect it 2 weeks later, but there are multiple items on this particular write up that were not discussed in the meeting we had. I am hesitant to sign it now because although I can and have taken responsibility for my short comings with this position, I don't feel comfortable signing it without addressing these items. Two of the bosses are out sick today and the other one I am not particularly comfortable discussing this with. Any advice?
