I am writing a novel and I recently discovered this word.
From my understanding, the definition sounds broad enough to be able to use this word loosely in place of co-workers.
With everyone sitting, it was difficult to see Angie, but after a minute or two, her pretty, little head popped up between my concomitants, and I did my best to suppress my smile.
Concomitants, of course, taking the place of co-workers.
The occupation is a politician (Councilman) in a radical Christian dystopian - his co-workers, of course, are also politicians as well.
If this is not correct, I will most likely go with "colleagues" despite wanting something more unique. "Comrades" has a negative connotation to it and words like "associates" and "peers" sound too vague and bland.
