Oh well at least they won't know that you haven't proudly displayed it!
I wanted to just slip out of the door when I took early retirement, but my immediate colleagues had organised some lovely thoughtful gifts - flowers, chocolates and a gift card, and a speech with some nice bits of humour in it.
However, the only acknowledgement from management was in a monthly newsletter, just stating "GrowingoldDisgracefully is leaving". No thanks, or acknowledgement of over 40 years of service or mention of any achievements. No doubt because the person writing the inclusion was the reason for my leaving earlier than I had planned.....
The final 'icing on the cake' was a letter from her, long after I had left, stating she had taken out a grievance against me and I was required to attend for a meeting. A control freak if ever there was one. The gist of my response I should think you can guess!
