Nearly half of British workers say that the moment in the week when they feel most stressed is just before lunch on Tuesday.
That, anyway, is the finding of a survey by the makers of a health supplement called Bimuno. They polled 3,000 adults and found that most workers coast through Monday getting their brain in gear and catching up with gossip from the weekend.
But everything comes to a head at about 11.45am the next day.
Graham Waters, of Bimuno-maker Clasado, says people generally begin to feel their workload and stress levels are getting on top of them by Tuesday.
The survey also suggests that one in five employees will leave the office late on a Tuesday as they work after hours to salvage their week.
