Britons seem to a moody lot, for a new survey has found that seven out of 10 office employees are in a bad mood the moment they wake up in the morning.
And almost half take their temper to work with them, the survey has found.
One in five admitted to falling out with their boss due to their moods and the same number had argued with their partner about their irritability, it found.
The figures showed tiredness, stress and hunger as the most common causes of moodiness.
Professor Geoff Beattie of University of Manchester was quoted by the 'Daily Express' as saying, "The findings paint a woeful picture of mornings, with so many starting in a bad mood and skipping the most important meal of the day."
Those who ate breakfast were less moody, with 63 per cent admitting to feeling grumpy compared with 74 per cent of those who missed the meal.
The survey found that four out of ten of the 2,000 workers surveyed admitted their bad mood affected their entire working day and even impaired the quality of their work.
