I have worked at my workplace for nearly 20 years and just celebrated a special birthday (50 😩) I thought we all were friends and have in past contributed to others who have turned 30/ 40/50 usually giving £5. However there was no collection for me and although one colleague got me a lovely present - that was it. There was no joint card or collection. I feel so disappointed and hurt - I thought I had friends at work but realise they aren’t really my friends. Should I just get past this and concentrate on my family- I’m feeling very resentful.
