It depends the context in which you cursed. As a curser (and manager), it's taken much worse in certain circumstances. I.e. "This fucking code" versus "I don't give a fuck what you have to say" or such, in the latter is more aggressive and directed.

An environment where cursing is a fireable offense is an environment I'd avoid, because there are limits to the demands of hypersensitive people.

Cursing aside, my worry is your hostile environment criticism might have a wider cause than a single word. Try to work on building positive relationships with as many people as possible. Smalltalk, interest in them and help in the context of the company are things to aim to build.
