@roger,
Yeah - but this is a small industry in a sense - some one always knows some one else. I know several years ago when we had a big relocation thing going on - this one guy that worked for me - he was not relocating so he was going on severance. I told him I understand he may not want to give 110%, but just to remember to keep up a good job as this is a small industry as he wasn't doing his job.
Wouldn't ya know - some one called me shortly after this conversation and "off the record" do you know so and so - I gave them the straight goods and said - I understand why his work his slacking now so I wouldn't hold it against him. Fortunately for him, I was an understanding person.
So yep you give the 2 weeks, shut your mouth and act appropriately. All the while flipping the bird behind their backs.
