Former night shift worker: We had bun sunday where we purchased buns for the entire shift to enjoy at end of shift. Also champagne thirsday where the entire shift stayed up the following day and went out to party together.
Friday Games! My team gets together and plays a boardgame. Lately it's been Gartic Phone, but we also like Code Names, Wavelength, Jackbox... Fun way to spend an hour on a friday
we have a 4pm zoom meeting in which we have to compliment at least 3 people we've collaborated with that week. The shortest it's ever been is 40 minutes.
Worked for a while at a company that created natural flavor extracts. A couple people worked with a client coming up with new flavored alcohols. On Friday afternoons they would make up small mixed drinks for people to try out and get opinions.
I used to work at a small IT company. Every Friday at 2pm the boss would stream The Big Lebowski over all of the office TVs and speaker systems. He had painstakingly cut all of the profanity out of the audio by hand.
You were encouraged to get a beer or two when the movie started. Then we just worked with the movie on in the background and sipped beer until 4pm when the office closed.
I can still recite The Big Lebowski, sans profanity, over 10 years later.
Pizza friday! After I switched jobs, the tradition is a bit on and off. New coworkers are not always keen. I have to bake my own pizza in the afternoon in those cases.
I worked somewhere where we used to have a toast run to the local deli and get doorstep toast. Then people would bitch about the toast not being to their exact specifications
