Pros
Very few pros except that you get a few discounts on Co-op food and other areas. The Angel square building is nice but the CIS Tower had mice.
Cons
This was by far the biggest career mistake I have ever made. I left a job to come to Co-op, however the practices that went on were so shocking that I would rather be unemployed than continue to work there. Firstly, the building was beyond repair (CIS tower) and should be demolished. There were mice, broken furniture everywhere and unsanitary conditions - no kitchen sinks so people used to leave sponges in the toilets and wash their mugs, plates, etc there. Secondly, however much the Co-op wants to say it's changed and is 'back to being co-op' it simply hasn't. The culture was shocking; people being wrongly dismissed, illegal practices, contractors being kept on for 3 - 4 years at a time on obscene day rates yet being asked to interview their permanent replacements (is it any surprise they delay filling these roles as much as possible?). Thirdly, the systems are so appalling that customer data is routinely at risk, so much so that I have ceased even being a customer of Co-op. I was advised by a few people (including ex employees and recruiters) not to move to the co-op and I ignored them, I really wish I hadn't made that mistake.
