A new report says the UK's long-hours culture could cause stress and low morale. Publishers of the report, the TUC, found the phenomenon was not only endemic among eager young workers aiming to impress in managerial roles. It also recorded that a quarter of a million more people aged in their late 50s and early 60s are now working unpaid overtime than were a decade ago. The TUC said the trend reflected people's concerns about income in later life.
