I was talking about this with an ex-colleague. We both left the same company within a few months (her voluntarily, me through redundancy) and had been there quite a few years (her 11 years and me for 7 years) and she has got quite upset that some of our ex-colleagues that she thought she was close with just haven't stayed in contact. Some have actually been quite funny with her. I am still in contact with other ex-colleagues from the same place and while we don't stay in contact every week, we normally catch up, often on email about once a month or more if there is occasion to.
I get the impression that for alot of people they are really not concerned about staying in touch - they make all the noises of 'we must do lunch' or 'lets get together for drinks after work' but when push comes to shove, people move on. I do try and make an effort but with some people it just seems wasted and I think you can only try so much and then have to forget about it.
What is the general view on staying in touch with ex-colleagues?
