I am not really that surprised abut Rob. I have met people like him before. In fact, I had a Manager like him, up until 2008. He made my life a misery and I had no option but to resign my job or risk mental illness myself
( actually, he was found out for what he was, and was sacked a year later ! )
He was a bully and became even worse as time went on. He was completely lacking in any empathy whatsoever.
But something that doesn't quite ring true in the Archers storyline is this...
Everybody, with the exception of Kirsty, seems to be completely taken in by him. Pat and more importantly, Peggy should have seen through him by now. There have been sharp words between Rob and Tony, and Rob and Tom but they haven't amounted to anything. Shula has also had a run-in with him and she is nobodies fool.
Now that Helen is unwell, Pat will want to visit her and Rob will try to put a spanner in the works about that. But if the scriptwriters allow it, then they will make the story even less believable.
There is also the unfinished business of the blocked culvert and the disappearing Polish worker ( whose name I have forgotten ! )
But its a good storyline and has succeeded in making Rob the most hated character in Ambridge for many a long year !
