Yeah. Unless they reach a divorce settlement the coach keeps getting paid. When they want to take a new job it's usually not a problem, because clubs are more than happy to get them off their payroll.
I could see labour law becoming an issue if Gladbach try to mess with rose after "sacking" him, but I'm no lawyer, so I have no idea how this would play out. And on what timetable: like if Rose needs three months to get his ruling he's fecked either way. In the end this won't happen anyway. Dortmund won't mess with their coaching position to save what's essentially a (very) large chunk of pocket change and Gladbach won't ruin their reputation either.
Exactly, that's why is interesting.
Usually it's in the former club's interest to get a sacked coach off the payroll, in this case it could become imaginable they would want to keep him on even to the degree to be able to claim a release clause, which of course sounds absurd.
But even then, there would be adivorce settlement, as you say, something like, they forfeit the release fee if Rose forfeits his compensation. Bottom line still, it's financially detrimental for Gladbach to sack him; if he stays onand the clause is triggered they straightforwardly collect 5m €.
And as for reputation, 5m € is a hell of a lot of money for Mönchengladbach.
But I'm asking because I don't really know how this stuff works.
There was the case with Tuchel at Mainz, but I think he decided to leave a season before his contract ended, he wasn't sacked. And then Mainz tried to block him from taking over another club during that remaining contract time, understandably.
