People doing temporary work or on fixed-term contracts could be at an increased risk of mental-health problems. Researchers at McGill University in Montreal used information from a national survey which followed people born between 1957 and 1964. They found that people in temporary work reported more symptoms of depression and psychological distress. It is estimated that 4.1% of people in the U.S. workforce - around 5.7 million people - are in such temporary work.
