Who'd want to be a BT Engineer
All the existing, qualified ones cost to much to keep, according to the Mgt. The solution is to 'manage' them out of their jobs by steadily increasing their targets. The aim is to replace them with less qualified people on 'cheaper' contracts or to force existing employees to accept changes to their contract.
Don't take my word for it. Just ask your local friendly BT engineer, the next time they visit, or not.
