Drinking at work is generally seen as a no-no - particularly if there's a safety aspect.
Recently, for example, two pilots were hauled from the cockpit of an Air Transat plane as it prepared for takeoff in Glasgow after passengers spotted them behaving oddly. Last year, another pilot was jailed for being drunk while flying.
Whether or not there's a clear safety issue, many work contracts specify that you need to be sober at work. However, it appears we don't take much notice, with a survey last summer from ACAS revealing that as many as 85% of people have been drunk at work during the last year.
"Just one person on the shop floor or in the workshop incapable through alcohol puts everybody at risk,' comments Mark Hall of Protecting.co.uk.
"In a bank or an office, just one wrong finger on a keyboard could cost thousands, millions, in lost trade. That's the cost of a pub lunch."
However, in some jobs having the odd drink at work is seen as perfectly acceptable; and there's even evidence that it can make you better at what you do.
Researchers at the University of Illinois found two years ago that 'moderate intoxication' made people better at a task involving spotting changes in a video. "Both the sober and drunk people find the same number of changes, but drunk people find them faster," said author Jennifer Wiley.
But for those resigned to a more conventional career, there's still good news. The Glassdoor recruitment site recently checked through its anonymously-contributed staff reviews and found that a surprising number of companies reward their workers with free beer.
