This problem I feel is not limited to Sprint. I worked for a call center in Canada for just shy of a year, selling domain names and support services. The micromanagement was endemic, and getting worse before I left.

At one point, after i returned after being in hospital for 4 days with a fairly serious medical condition,(and, yes, i had informed my section manager) I was told that this amounted to "abandonment" and although I wouldn't be fired THIS time, a note was entered in my file!!!

Many of the really terrific people I worked with had university degrees, or were in school. (At the time I had my undergrad degree in Science and an MBA) but most were looking elsewhere because of the poor management. The last i had heard, the company had been sold, and much of the work was being outsourced to India
