Assuming it's true they had their wages reduced in the crisis, it's absolutely disingenious to claim that a return to higher wages post-crisis would be undeserved profiteering. They did share in the losses.
Accepting the risk of losses is why owners have a legitimate claim to the profits. Workers take a guaranteed paycheck which shelters them from losses in bad years and forfeits their claim to profits in good.
It's just great when workers accept pay-cuts in bad times, just for people like you claiming that this is just normal, no loss, and certainly no reason to restore their paycheck when good times are returning.
