it's an interesting tactic by Rob.
I think this a fair summary.
It's a bit like having 10 tenants in the house
The landlord has said to Rob, whom has been a problem child in the past. I know you have potential as a tenant and pay your rent but I'm watching you buddy.
You are on trial and can stay for four years but you can't smoke in the house, get drunk, have orgies and go of the rails.
Unfortunately Rob has fornicated, drunk and smoked. Not quite to death but fairly close.
He knows he mot met his metrics and in two years is bound to be kicked out. In short he knows he's fudgeed
He therefore gangs up with the other tenants, acts as top dog, starts swinging, blames the landlord and threatens to beat him up and take over his house.
Have I missed anything?
No, the landlord can afford to fix it from the income he receives from the labour the tenants do on his behalf (ie their employer) but he spends it elsewhere and chooses to neglect them.
