Librarians are the most unhappy with their workplace, often finding their job repetitive and unchallenging, according to psychologist Saqib Saddiq.
He will tell the British Psychological Society that one in three workers suffer from poor psychological health.
The study surveyed nearly 300 people drawn from five occupations.
They were firefighters, police officers, train operators, teachers and librarians and were intended to cover the spectrum, with the librarians first-thought to be the least stressful occupation.
Repetitive and unchallenging describes my current situation perfectly. But I know from experience that it doesn't have to be this way. And anyway that's all going to change in a couple of weeks.
