Pros
I have worked for BT for 1 and a half years and in that time have found working in BT is a nice and comfortable enviroment to work in. Good training packages, nice staff attitudes, the willingness to help you develop and give to the room for improvement.
Cons
There are of course downsides to working for BT. You only have the scope to move upwards within your department and not to other departments, You have a limited work plan which you have to stick to and they have a tendency to make you work more than your allotted time frame as there is always things which take you over your scheduled finishing time. Not enough opportunities to become fully employed by BT as workers are mostly contractors looking to get into full time employment with the company.
