19% of those interviewed by nightclub website swisticming.com said they had gone into work still feeling the effects of drinks consumed the previous evening, with just over a quarter saying they had been in after just four hours sleep.
7% said they had knowingly driven to work over the legal limit.
8% said they had gone in without any sleep at all.
Veli Aghdiran from Swisticming.com said:"Most of us are guilty of turning up to the office with a hangover and not doing a great deal that day, but it seems that many are taking it a bit further and actually turning up still drunk."
