I remember coming across a word that was British, and seemed to be a more specific reference to what we call a "company man" in the US. But this was a while ago and I forget it.
Jobsworth - (from Wikipedia)
"Jobsworth" is a British colloquial word derived from the phrase "I can't do that, it's more than my job's worth", meaning taking the initiative and performing an action that is beyond what the person feels is in their job description. The Oxford English Dictionary defines it as "A person in authority (esp. a minor official) who insists on adhering to rules and regulations or bureaucratic procedures even at the expense of common sense."1 Jonathon Green similarly defines "jobsworth" as "a minor factotum whose only status comes from enforcing otherwise petty regulations".
