Why will Curley keep quiet about what Leannie did to him and not try to get George and Leannie fired?no

When Curley attacks Lennie and he fights back at George's direction and crushes Curley's hand, it is Slim who convinces Curley not to turn Lennie in.  Slim tells him to say he got his hand stuck in a machine, and if he doesn't, he and the men will tell what really happened and Curley will be laughed at by everyone, something he fears a great deal.
