The lunch-hour, which is a traditional part of the working day, has for most been shifted to an earlier time due to too much work pressure.
According to a survey by sandwich chain Subway, around three million staff are regularly forced to take a "mid-day break" before 11am due to the increasing work pressure.
A further ten million employees sometimes do not get a break until after 3pm, and around 28 percent of workers in the poll of 2,000 people said their employers discouraged them from taking a full hour at lunchtime.
"These results reflect ever increasing work pressures," the Daily Mail quoted Manaaz Akhtar, head of marketing at Subway, as saying.
Another survey found that many workers cut short their lunch break to try and impress their bosses, or use it to do personal chores rather than having a proper meal.
