One-fifth of managers are worried about employees who work from home, according to new research.
The survey by technology firm Mitel also revealed that 37 per cent of bosses are concerned that staff who work from home will take advantage of their new surroundings to take a longer lunch or undertake other personal tasks.
Despite this, 68 per cent of workers said they think homeworking helps them to be more flexible, with 41 per cent stating that working from home makes them more productive.
"It comes down to a matter of trust. If you trust and respect your employees to get the job done, they will trust and respect you in return and do the best they possibly can, regardless of whether they are in the office or not," said psychologist Dr David Lewis.
A recent report from BT Business suggested that many small business owners believe the use of broadband helps to boost flexible working practices.
