My mate works for Openreach. As a worker, you get shafted every day, by being expected to be in two places at once, and spending the minimum amount of time at each job, to maximise the Shekels for the firm. And all while they shaft you by making your conditions as crap as possible so you end up just leaving without the redundancy they will never, ever give you, because your worsening pension conditions demand it. You basically just choose your monment to jump before things get even worse.
I don't work for Openreach, but the same is happening to me. I'm not saying where I work, although some of you know.
I believe that although Openreach aren't BT as such, they are owned by BT and they are effectively ex-BT.
The way they treat their customers is almost certainly down to the incompetent, money-grabbing self-serving, bean-counting management.
