I worked in connect (customer service, over the phone) for 2 years. I had a string of terrible managers who would mark me down for the slightest thing, where other managers would say I did nothing wrong. I was consistently asked to go above and beyond my job role but was marked as an under performer in a yearly review which stopped me progressing. Very good benefits and salary however. Also very supportive if you are in poor health/struggling with mental health. I was given time off with no hesitation plus they arranged councelling sessions for me when I went through a tough time.
Overall good, as long as they don't hold you back
Great benefits, flexible with shifts, great work life balance
