strange leaving gifts or nothing at all

That's terrible Judy54 How thoughtless.
I must have been lucky I got a dishwasher ( request ) tickets to Phantom in London and some jewellery. I had been there over 30 years and it was some time ago.

It is strange and not very kind.
I had gifts, very thoughtful/witty speech by my director and a pub send off.

I was also retired due to ill health following an assault at work and didn’t even get a get well card. That was after 20 years too. It was very upsetting.

Goodness that's awful. I was in my job for over 35 years. I got more lovely gifts than I could carry.

Nothing after 20 yrs I took ill-health retirement. I was off sick due to impending surgery didn't even get a card.

I am sorry, it doesn't make you feel valued does it.
When my husband had to retire due to ill health after twenty five years he got sod all too. Management should make sure people's loyalty and time are acknowledged when they leave - but as you were made redundant I assume everyone was feeling rather upset about it all.
