I also worked for an health insurance company, tho my experience was less extreme than yours it still sucked ass.
I worked the phones, and was hired together with a couple of other students through a student-oriented job agency. They lured us in with talks about how you can “really help people”, and that pretty much every income call was “always positive”, and naive young me believed it. I found out real quick that, surprise surprise, people don’t call their insurance to tell them how happy they are with another out of pocket expense. And the helping people part was bullshit too. I couldn’t waive fees, or approve insurance payouts, and when people wanted a payment plan I just filled in the form on the companies website for them. Wanted a payment plan that was different from the options on the site? Tough shit, either accept it or be prepared to be on hold for an hour while I transfer you to the department that might do it for you after grilling you for making, in their eyes, the bad financial decision of being alive.
I was lucky enough to never have been threatened on the phone, altho I couldn’t say the same for my fellow student colleagues. When that was brought up with management they acted like it was the first time ever in the companies history, which I saw through immediately.
Since we were technically making financial decision for other people, we had to get certified. The process costed around 400 euro, but was refunded by the company on the condition that you worked there for at least a year. If you quit after 9 months you’d get 75% back, 6 months 50%.
I quit the day after being employed for 6 months, and have skipped past every call center job I have come across since.
I had to quite literally push people aside in a crowd because even tho I was wearing a work shirt they refused to move when I had to get to the stage. That made me mad ass hell, I think I would have exploded if I was in your position. You handled that really well.
Did you have to take down the lights with you? Or were they of the venue?
