Many workers do not want their boss to go to the office Christmas party, fearing they will spoil the fun or even spark a violent reaction, according to a new study.
A survey of 2,000 adults by restaurant chain TGI Friday's found that one in three believed having their manager around stops everyone having fun.
One in five said they do not want their boss to attend the office Christmas party at all and 27% are worried they might not be able to resist telling them exactly what they think of them.
One in eight was worried things could turn physical, while 1% revealed they had quit their job at the office party.
Darrell Wade, commercial director of TGI Friday's UK, said that bosses need to lighten up.
He advises them to indulge their staff and perhaps even pick up the tab if they want their workforce to have a good night at the annual festive bash.
"The office Christmas party is all about cutting loose, having fun and celebrating all the hard work the staff have put in over the year," he said.
"Bosses who want to join in the party should give their staff what they want, which is a mix of a lively atmosphere, great food and indulgent cocktails, and of course, look on the bright side, over half the population don't mind the boss coming along, even if the only reason is to pick up the tab."
Meanwhile The Forum of Private Business is warning business owners to be aware of Christmas pitfalls, ranging from health and safety risks to staff rotas, which could leave employers open to litigation and staff disputes.
