On a spectrum with Goober on one end and Soianka on the other, I'm a lot closer to the Goober end.
Benefits given by one party to another are voluntary (gifts) or contractual.
The cessation of a voluntary gift is not punishment unless a recipient has unjustifiably developed a sense of entitlement to the gift, and in any case voluntary gifts are not enforceable.
Contractual benefits are defined by the contract. I haven't seen the contract. All those saying lawsuits would be in order please post up the contractual terms that you think have been violated.
As for a civil rights claim...that helps me understand a lot about this Board
