Only 20 per cent of dads take advantage of flexible working laws.
This is according to Workingmums.co.uk's annual survey, which found that four per cent had a part-time role, while 16 per cent have another type of arrangement with their employer.
Despite the fact that 35 per cent of females are now the main breadwinners – up from 30 per cent last year – it is still members of this sex who usually seek out flexible working.
When asked what makes for a family-friendly employer, the most popular response was one that offered full-time flexible jobs.
Gillian Nissim, founder of Workingmums.co.uk, noted there seems to be a significant number of companies resistant to change.
"There is still a long way to go to change our work culture so that both employers and employees benefit from smarter working practices," she added.
However, Ms Nissim did welcome the recent announcement by the government that will see a radical shake-up of the current leave arrangements, which are designed to make it easier for mums and dads to hold down full-time positions.
