I've been confused about Rob's employment status for a while.
At first Rob was employed at Berrow Farm and Helen worked in the Bridge Farm family business mainly running the shop and making cheese. Rob did put his oar in with shop business decisions though I don't think he had any real status to do so.
Then Rob loses his job. Helen continues to work at the shop (when Rob lets her) and presumably continues cheese making (Rob seemed to have less of an issue with this or perhaps was less confident that he could take it on). Rob shows no real enthusiasm for seeking another job.
Bridge Farm then decide to open a Farm shop to replace the shop in town, which isn't doing so well since Rob's started interfering in it.
Rob volunteers to be site manager for the building of the new shop. Before he volunteered for it it wasn't at all clear that a site manager was needed. Pat and Tony live on site and are in theory retired and available to advise Tom and Helen as needed. They surely have as much building expertise as Rob. It seems to me that Rob created the site manager job and was given it without any real thought. Did he have a formal contract and was he paid for it?
After the shop was built Rob started helping with and eventually took over Helen's role. Again I'm not quite sure how and when the decision was made to employ Rob or whether Tom and Helen just let it happen. I'm guessing that they didn't have a formal application process, take up references etc. I wonder if they had whether Charlie would have had a quiet word.
If Rob has a formal contract then it's the first we've heard about it. I suspect that Helen's employment status and role in the business is much clearer as it would have been dealt with properly (I hope) when Pat and Tony decided to hand the business on to Tom and Helen.
Rob's position is completely inconsistent with what Tony and Pat intended to do. He's effectively turned a two person (Tom and Helen) business into a three person (Tom, Helen and Rob) business. As he completely dominated Helen he then had two votes to Tom's one and therefore controlled the business.
In the meantime, Johnny, who arguably should have been given his father's share in the business and who is related by blood rather than a short and very recent marriage is left completely out in the cold.
In a way I think that the whole Bridge Farm family (not just Helen) has been groomed and manipulated by Rob.
