There are no friends at work, only people who behave professionally and those who don't

1. disappointed that when i got fired, my work friends all ditched me
2. non of them like my posts on LinkedIn either

I was told that this was bc they knew the boss was mad at me and so didn't want to be seen to support me

Rubbish. Many people have many good friends at work.

However, yours may not have been.
