Retired last October after 38 years with BT, latter years Openreach as a C3
Not bad employers overall, but there are some pretty awful 1st level line managers who will do anything to get their bonus payments
Watch out for the performance and attendance procedures, often used to manage(sack)people from the company.
Promotion is pretty much a non-runner so expect to remain at the same grade for many years. Pay is decent enough espcially if you can achieve what was the old Technical Officer grade (C3)
Join the CWU, again not great and in my opinion recommended acceptance of too many loss of terms and conditions, but better off in than out
Employe benefits ok, free broadband and if the price is right sharesave schemes are worth looking at
