Sadly, working conditions in the Royal Mail are draconian, to say the least. There is most certainly bullying in the workplace which is largely ignored by both management and the union reps.
My sister is a postie, and she has, for well over 10 years had to endure sexism and bullying at work.
Getting bitten by dogs, etc is a job hazard all posties understand. When on one occasion, she had a bad fall in someone's garden, because it had all been dug up, and she'd hurt herself badly, and had to go to hospital she was in trouble for time off work.
When she was forced/bullied back to work a few days later, still injured and unable to do her job properly, she was set upon by someone's very large dog and sustained a big old bite to her leg; another trip to hospital, tetanus, stitches, the lot.
She got a written warning for this.
The whole communications worker system (i.e. post/BT/O2 jobs) are ALL like this. They are all under the same union too. Unfortunately it seems to be turning into a militant organisation as they are so highly led by the union and not following standard lawful working practices. I am sure there are a few hundred loopholes they have exploited in order to get away with the poor treatment of staff, but in essence, there are many employment laws clearly broken to anyone of an objective viewpoint.
Adam Crozier couldn't run the FA, he certainly wasn't a suitable candidate to run the Royal Mail either...what credentials does he have???
It's sad that it is inevitable the RM will be broken up/sold off.
