I'm looking for an adjective that describes a group of people who don't get along, who work poorly together, who don't necessarily like each other. A word that means or implies interpersonal difficulties, but not ones that are impossible to overcome.
Several ____ coworkers caused the project to be delivered late.
Some words I've come across that I don't think fit:
Inharmonious: This is probably the closest, it just sounds very clunky. I wouldn't use it in everyday conversation. If I can't find anything else, this is probably what I will use.
Incompatible: This has a more absolute connotation that I want. If two things are incompatible, there is just no way around it.
Antagonistic: Close, but it doesn't convey the "interpersonal" part. If I said "several antagonistic coworkers," I'd be more inclined to think they were antagonizing someone outside of the specified group of coworkers.
