Just an example of how management works in an NHS trust
There's an admin management role on band 4, the person in this role is an absolutely incompetent malcontent who gets all the staffs backs up, causing them to go off sick or put complaints in etc
Does NHS Trust deal with the problem and get rid of the member of staff down the disciplinary route? No. NHS Trust Management decide the best way to approach this is to remove the people that complained about the Band 4 manager and make them responsible to a new Band 5 manager, which is a new role they are creating and the band 5 manager will also be responsible for the band 4 manager. All the staff that didn't make a complaint report to the band 4 manger as before.
Even though those staff aren't strictly part of the band 4 bully's role, that person still has a say and still makes peoples life as difficult as possible
Here's the kicker. The band 4 manager was employed in a completely flawed recruitment process, this process is exactly the same when they employ the band 5 manager and the band 5 manager turns out to be lazy and useless. You now have a lazy get who can't be arsed managing the bully.
The good staff have already left at this point. The flawed recruitment process continues and more useless staff are employed to be bullied
Trust management are happy because complaints have reduced.
