Resignation in thank god!
He did take it OK and seemed as if he was half expecting it anyway.
What has annoyed me is that after he sent me written confirmation of the details we discussed in the call we had, cc'ing in the senior managers in my dept but he has completely made it look like he wasn't the problem at all. In fact he's made it out in the email as if he's done everything by the book and has made it out as if he offered unlimited support etc etc. He also accused me of not responding to emails in a timely fashion
This was definitely not the case. Obviously he's wrote all that to "look good" in front of the senior management team of my department.
At least only a month to go anyway!
