The report, by the charity Working Families, found that parents earning over £70,000 a year are more likely (47%) to work flexibly than those who earn between £10,000 and £40,000 - according to BBC News.
The research – based on a poll of 1,000 working parents – also found that most of them worked over their contractual hours, with a quarter putting in at least five unpaid hours extra a week.
The Confederation of British Industry argues that employers that don’t offer flexible working are missing out. It says "offering jobs at every level on a flexible basis will help companies to recruit and retain the people and skills that are needed to compete."
Flexible working can include part-time hours, home working, flexi-time and staggered hours.
With the rise in video and audio conferencing software, people can now easily dial in remotely to work. And while flexible working hours may not be possible in every job, there are many roles where the option works well.
