How do slangs and colloquialisms illustrate class and social conditions in the novel?

Many of the slang terms have to do with getting fired or demeaning language about women. Getting "canned" is often a term used for getting fired. All the men desperately need these jobs and getting "canned" is not a good thing.

"Slim, will we get canned now? We need the stake. Will Curley's old man can us now?"

Women are openly objectified in this story, especially in a ranch full of men. Curley's wife is referred to in terms of her sexuality and little else.

“Well, I think Curley’s married… a tart.”

“Jesus, what a tramp.”
