Years ago I worked at an ISP tgat went through a merger. They decided they were going to outsource customer service to another company.
We all got nice severances and 3 months prior notice where we basically didn't work because all calls were being routed to the new call center and we were just backup. What a great 3 months. We had card tourneys, spun up the companies old game servers and ran minecraft (alpha) on them, lots of fun.
Get laid off, fast forward a year and the outsource company has taken an 86% approval ratimg down to the low 30s.
They hired a lot of us back to completely rebuild the service department. I was tier 1 and got a 76% raise. I imagine others got better.
