Employees are working and worrying more, often for no financial reward, as the downturn begins to bite, according to research from Friends Provident. The Britain Under Pressure survey found that UK employees are working an average of seven hours’ unpaid overtime each week, losing out on a combined £23bn a year. The research also revealed that 25% of adults plan to work longer hours over the next six months, while one-in-eight of the 2,713 respondents intend to take on a second job.
