That's the word from researchers at Clasado Ltd., the U.K. company that makes the health supplement Bimuno, who surveyed 3,000 British workers and found that mid-morning on the second working day of the week is the moment when they feel the most pressure.

Conventional wisdom maintains that Monday is the most stress-filled day. But the London Telegraph reports that most workers coast through Monday, spending the day getting their brain in gear and catching up with gossip from the weekend through social networking sites. Fully 53 percent of those polled admitted they don't do much work on Monday, and 10 percent said they spend a lot of this work day on Facebook and Twitter.

In other words, limited work happens on Monday. And on Tuesday, reality sets in. You go through a few e-mails. Straighten up your desk And then whammo! Just before lunch, it hits. Yikes! There is so much to be done!

"Traditionally, people associate Monday as the worst day of the week, but this doesn't seem to be the case. Coasting through Monday means we're worse off on Tuesday, both in terms of workloads and stress levels," Clasado's Graham Waters told the Telegraph. "We lead such fast-paced lives that stress naturally runs side by side with this, especially when it comes to work. Tuesday at 11:45a.m. seems to be the time in the day when the real workload for the week hits employees, and as a result stress levels rise."
