I've been sitting on this for a long time and I felt so guilty. I do not know how to get rid of this feeling.
Basically, it was 4 years ago now. Something happened in one of my job. I left. But, I did add some ex-colleagues onto my FB. I do not know why, but I kind of felt I wanted to continue my friendships with them, but then they did not. Nor did they know or listened to my side of the story. Even though, I have never told them what happened, and I do not know if them knowing will also affect their employment too. One ex-colleague never knew this and he took offence and actually blocked me. 2 other friends were more stoic, and did not comment. One or two colleague I do feel some resentment towards because I basically saved their job for them. In hindsight, I felt like what I did was an injustice to myself. e.g. taking the blame when it is not mine to do so.
How do you balance work friendships, and can you ?
