Bored man sitting next to pile of workIt is unlikely that anyone who works would consider Monday to be a good day and it can take a few more coffees to get up to speed after a lazy weekend.

But this isn't any old Monday – this, according to a new survey, is the "most unproductive day" of the entire year.

Yes folks, it seems the changing of the clocks and the prospect of the long, dark evenings ahead is leaving us struggling to deal with the Monday workload and researchers say that productivity will drop by a whopping 50 per cent this week.

The study of 2,000 workers comes courtesy of Promotur, The Canary Island tourism board, and reveals that not only do 52 per cent of workers confess to struggling with their work-load today, 14 per cent claim that last year's 'unproductive Monday' was so bad that they had been hauled before the boss over it.

And for the eight per cent who simply can't cope with the onset of winter, the inevitable sick day seemed the only option.

Dr Christian Jessen, of Channel 4's Embarrassing Illnesses fame, told the Telegraph: "The Winter Blues are no joke.
"They can affect your work performance by making you unable to concentrate and carry out your normal routine, your relationship by affecting your libido and your social life by making you feel irritable and anti-social.

"Feeling low as the nights draw in and the days get shorter is something many people experience, but some will struggle with lack of motivation, tiredness and depression."

And Dr Christian went on to explain that winter is tougher on some than others.

"If you find the winter months tough, particularly during December and January you may suffer from Seasonal Affective Disorder, which causes a low mood caused by the lack of light during winter," he said.

"If these all ring bells then you may be a sufferer and should consider ways you can get more light into your life over winter."

So as long as you get out of the house, it sounds like that 'sick day' isn't such a bad idea after all.
