For me it was the collective solidarity during the manual data entry shifts we did when elections came around. Those were some of the most soul crushing experiences of my life, and the incredible feeling of coworkers you didn't even know that well covering for you as middle management wondered where I was (I had to take a short bathroom break because I couldn't take a leak for hours) were so heartwarming. Of course there also was all the bad stuff: lying to customers who were having real problems that you couldn't do anything about, being insulted by people you called for a survey and you can't even seriously argue against them, terrible pay, the list goes on. If you have anything to contribute, please do so! I'd love to hear your perspectives.
