The research shows men are likely to drink more than they intended at after-work drinks compared with women, although over half of these only did this because they felt under pressure to buy-a-round every week.
Siobhan McCann, head of campaigns and communications at Drinkaware, said: "There is nothing wrong with going for a drink after work, but for some people, especially ones just starting their career, it can be tricky to see the line between having a laugh and embarrassing yourself in front of colleagues."
The research did show some encouraging figures. Many 18-24-year-olds are already making attempts to display good work drinks etiquette, particularly young women:
55% of young women stop drinking when they've had enough, versus just 42% of young men.
47% of young women make sure they eat a good meal before going out, compared to just 37% of young men.
35% of young women try to drink slowl, versus 29% of young men.
Michael Gentle, head of consumer marketing at online job site, Monster, said: "Socialising with colleagues is an important part of working life, often boosting employee engagement, morale and team bonding. But losing your composure on a night out could mean losing the respect of your colleagues or causing long-term damage to your reputation."
The research was conducted for Drinkaware by ICM in August 2012. It interviewed 2,000 UK adult drinkers aged 18-24 in an online survey.
