WORKERS over the age of 56 are less stressed then their younger colleagues, partly because they are looking forward to retirement, Research published today shows that workers' stress levels usually increase as they get older, but then fall when they reach their mid- 50s.

Psychologists from the Universities of Manchester, Liverpool and Lancaster studied 4,700 administrative staff and secretaries and found that older employees had a different relationship with work than younger staff. One explanation could be that the under-25s did not expect to have much control over their work, according to the study presented to the British Psychological Society's occupational psychology conference in Bristol.
