jobsworth

A jobsworth is a person who uses their job description in a deliberately uncooperative way, or who seemingly delights in acting in an obstructive or unhelpful manner.

"Jobsworth" is a British colloquial word deriving from the phrase "I can't do that, it's more than my job's worth", meaning that taking the initiative by performing an action, and perhaps in the process breaking a rule, is beyond what the person feels their job description allows. 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." Jonathon Green similarly defines "jobsworth" as "a minor factotum whose only status comes from enforcing otherwise petty regulations".
