Pros
The people at working level are generally great. A few "hangers-on" but most of these have been cleared by previous HR schemes.
Cons
Central HR are currently on a savage and brutal people cutting exercise. Jobs disappear during the process and people are put into a position where leaving is the only option. The current process is illegal according to the unions but they just recommend people take the cash rather than fight it in the courts, as you won't get anymore. Good people with excellent track records are being targeted because they are viewed as being overpaid by BT (above the new pay range). Salaries are slashed, leave is slashed, pension is now worthless, healthcare and car benefits also cut. People leaving with boxes under their arms in tears. Appalling and unethical behaviour by a once good and ethical company. Be afraid, very afraid...
