More than a third of British employees (36 per cent) are eschewing the canteen and choosing to bring a packed lunch to work instead.
The poll from United Biscuits showed that workers were turning away from the canteen for a range of reasons to save money (53 per cent), to be more healthy (20 per cent), or because they were disappointed by the choice available to them (32 per cent) when buying lunch out.
As time-poor workers spend more and more time in the office, a quarter of those surveyed said that they brought a packed lunch as they resented spending time stuck in queues.
However, those who did bring packed lunches had trouble leaving them until lunchtime with 66 per cent of them eating a considerable amount before 12 o'clock.
"This research shows that adults in the UK are increasingly dissatisfied with the cost, quality, convenience and choice available to them when buying lunch out, providing food manufacturers with a huge opportunity," said marketing director for United Biscuits UK, John Eggleton.
Those living in Leeds were most likely to bring a packed lunch, with 50 per cent of residents doing this every day. The survey also found that financial services employees were most likely to bring a sandwich to work (82 per cent), while sales and media professionals were most likely to bring a salad (45 per cent).
