It's enough to make you choke on your sandwich - employees who do not take a break for lunch are doing an extra 16 days of work a year, research suggests.
And, to make matters worse, academics have warned that it could harm our health.
A poll of 1000 employees found that 60 per cent eat at their desks every day.
Two thirds leave the office for just half an hour or less, despite being entitled to an hour. Those who do make it out are far more likely to leave to meet professional contacts or clients than taking the opportunity to relax.
The researchers calculated that staff who eat in the office are working an extra 128 hours every year - the equivalent of 16 eight-hour days.
