Looking for a short story I read years ago.

Don't have many details, sorry, and I thought it might have been a Stephen King short, but can't find it amongst his writings. It had, I believe, a one-word title and took place in the future. There was something about a union and a labor dispute that led to the main character locking out the union members(?) business(?). Eventually, he gave up the password, which was the antagonist's name, and the antagonist was torn limb from limb. Thanks to anyone who can remember this one.
