It isn't a prerequisite to like your colleagues. And that doesn't just apply to offices up and down the country.
Many football teams, including Manchester United, have boasted teammates who haven't always been the best of friends.
Here are some quarrels to have emerged from Old Trafford over the years...
Teddy Sheringham and Andy Cole
Teddy Sheringham and Andy Cole were teammates at United for four years, yet they never uttered a word to each other.
Their feud dated back to when Cole made his England debut in a friendly game with Uruguay in 1995.
Cole, who had just signed for the Old Trafford club from Newcastle United, replaced Sheringham off the bench, but felt the latter failed to show any kind of acknowledgement.
The striker recalled: “He was going to be substituted for me to come on to replace him, and he snubbed me on the line.
“I just thought to myself, 'I'm making my debut here and Wembley is a packed house.' And I felt so small.”
Cole must have thought the worst when United splashed out £3.5 million to sign Tottenham Hotspur striker Sheringham in the summer of 1997.
But the duo regularly played alongside each other, winning a Champions League, three Premier League titles and an FA Cup.
Their 24-year-feud was put to bed in 2019, however, when Sheringham revealed that they had shaken hands.
“You get on with some people in the workplace, but some you like don't like and don't want to be around,” Sheringham said.
“That was the case with Andy.
“We just didn't click, but we've made our peace.”
Sir Alex Ferguson and David Beckham
Once one of the most famous footballers on earth, David Beckham's 12-year stay at United came to an end in 2003.
He had enjoyed adulation from the Old Trafford faithful, while enduring hatred from supporters of other clubs.
It is known that Sir Alex was concerned about Beckham's celebrity lifestyle, influenced by his wife and ex-Spice Girl, Victoria.
This one is perhaps the most talked about of Ferguson's dressing room bust-ups, which came after the United manager told Beckham he was at fault for a mistake against Arsenal that knocked the Reds out of the FA Cup.
The England midfielder disagreed, with Sir Alex describing what happened next in his book 'My Autobiography'.
“Between us on the floor lay a row of boots,” said Ferguson.
“David swore. I moved towards him and, as I approached, I kicked a boot.
“It hit him right above the eye. Of course, he rose to have a go at me and the players stopped him.”
The paparazzi were out in force the next day, snapping Beckham with an inch-long surgical tape above his eye.
He joined Real Madrid a month later, but has since reconciled with his former boss.
Roy Keane and most of his teammates (plus Sir Alex Ferguson)
Combustible is probably one of the softer adjectives to use when describing Roy Keane.
There is no doubting he is among United's greatest ever players – and captains – but the way he departed Old Trafford in November, 2005, still leaves a bitter taste in the Irishman's mouth.
Tensions had mounted when Keane, who won seven Premier League titles at United, fell out with Sir Alex at the club's pre-season training camp in Portugal, complaining about the facilities.
He followed it up by telling the club's in-house television station, MUTV, that he would be prepared to move on.
But it was another appearance on MUTV a few weeks later which was the final nail in the coffin.
After a 4-1 defeat at Middlesbrough, Keane was reported to have criticised the performances of his teammates, including John O'Shea and Darren Fletcher, as well as apparently saying of Rio Ferdinand: “Just because you are paid £120,000-a-week and play well for 20 minutes against Tottenham, you think you are a superstar.”
Sir Alex sent his former leader on the field packing and in September, Keane continued to pour fuels on the flames when he declared that he will never forgive his ex-manager.
