Behavioral economists have studied this type of change and it can seriously affect relationships (there was a famous study of an Israeli day care that started charging parents a fee if they picked up their child late, then tried to change back to the previous policy). Having a benefit then losing it makes people feel like something is being taken from them (even if Jet can still have off-campus happy hours).

That said, I don't know how much I care. WalMart has a reputation and if you are part of a company that chooses to be bough out by WalMart, you have to expect that some big things will change. Hopefully the Jet execs set expectations correctly.
