I'm only an adjunct so any severance issues don't apply to me... but there is an open question if the arbitration agreements signed with EDMC when originally hired transferred over to DCEH. Nor am I a lawyer but am someone quite interested in it.
I certainly never signed anything new once the buyout happened. To my knowledge, full timers did not either.
“The policy may be debatable but the law is clear: Congress has instructed that arbitration agreements like those before us must be enforced as written,” Justice Neil Gorsuch wrote for the majority in a 2018 SCOTUS case. But the arbitration agreement as written would have been exclusively with EDMC.
I wonder if an argument could be made that the cause for any class action happened after DCEH took over.
