I have been with my current employer 6 years in a number of roles and am now fairly senior.
In that time I had a baby and a milestone birthday and now am leaving in a week and know I wont get so much as a card
I don't think im unliked. I have colleagues who are genuinely sad that I am leaving and who have invited me to social events outside work eg weddings christenings birthdays and even home bbqs!
Its not a culture thing as a colleague had a big bday (a decade above my own) and we chipped in for a communal gift. This was 2 months before my own but I never got a card?
I give colleagues birthday cards and have organised leaving cards and birthday gifts for groups
I manage a team of 6 and at christmas one of them said "i was in charge of your Christmas gift but not had a chance so were going to do it in the new year..." and nothing!
So AIBU to think I should have had some form of personal token after and during 6 years
