Coffee lovers are higher paid than tea fans but those who like a brew are more laid-back in the office Coffee drinkers earn £2,160 average more than tea drinkers 84 per cent of tea drinkers claimed to be team players compared with 74 per cent coffee drinkers Coffee drinkers in the survey came out as argumentative; tea drinkers were laid-back at work Think carefully how you take your caffeine in the morning - a choice between tea and coffee can determine your salary and popularity at work. Employees who drink coffee are more likely to be hot-headed, argumentative and live on a knife-edge, researchers found. But they have bagged more pay rises over the last five years and earn on average £34,490 a year - £2,160 more than tea drinkers. Name your poison: Coffee drinkers tend to earn more than tea drinkers, yet still be later for work Those who prefer a cup of Rosie Lee are less likely to be promotion material, but tend to be fair and laid-back at work. The poll by Zip HydroTap instant water heaters also found that executives are more likely to prefer coffee, but tea drinkers were "the life and soul" of the office. And 84 per cent of tea drinkers claim to be a team player compared to just 74 per cent of coffee fans. Fewer coffee drinkers said they were "very stressed" - ten per cent compared with 12 per cent of tea drinkers - but coffee drinkers were more likely to be late for work, despite their caffeine fix. Zip spokesman Nick Taylor said: 'Most workers need a cup of tea or coffee to get them through the day and most people could instantly define themselves as either a tea or coffee drinker. Workers up and down the country will be able to relate to the findings of this poll. We all know the coffee fiend who needs their caffeine fix before they start the day or the tea lover who has strict requirements about how their brew is made. Cup of calm? Tea drinkers were reported to be more likely to feel stressed The typical tea or coffee drinker has between three and four hot drinks everyday but tea lovers were more likely to combine a brew with a good gossip. And when it comes specifically to whose round of drinks it is, tea drinkers are more likely to row with colleagues. Yet the average worker makes just one hot beverage for their team in a day and 72 per cent said they need a drink to "perk" them up and stay motivated. Tea drinkers dressed in a more casual and cool fashion around the office whereas coffee fans described their style as funky and edgy, the research showed. Those who favour a cuppa were more likely to drive in to work, whereas coffee fans were more likely to hop on the bus or train. Nick Taylor, Sales Director for Zip Heaters UK, said: 'The research shows there is definitely office politics when it comes to doing the tea round. We have all been in the situation where we have a heavy work load and are getting hassled by team members to make a big round of tea. 'But it's pretty harmless if it's just playful office banter.'
