Legislation giving employees the right to request flexible working has failed to increase take-up, according to new research.

The findings suggests there has been no significant overall increase in the number of employees working flexibly since the changes came into effect four years ago.

Researchers found that when comparing the same people in 2010 and 2015, there was little change in the uptake of flexible working - those working flexible start and finish times, fewer hours, or from home.

In 2010, 44.1 per cent of all employees worked flexibly, and by 2015 the figure was 44.3 per cent.

While there were small changes in some areas, such as decreases in the use of term- time working and job shares and increases in the use of flexi-time and home working, the changes were not statistically significant, apart from an increase in home working.

Joanna Wilson, who analysed survey data from a sample of up to 24,736 UK employees for her PhD at the University of Manchester, said that the Conservative-Lib Dem coalition Government brought in a statutory right for staff to request flexible working in June 2014.

She said: "The extension of the right to request flexible working to all employees, regardless of caring responsibilities, was aimed at increasing its use in the hope that this would lead to the creation of better paid and better quality flexible jobs, thus helping close the gender pay gap.

"On the whole, the use of flexible working in the UK appears to have changed very little from 2010 to 2015, and there is no early evidence of an increase since the extension of the right to request legislation in 2014."

She said that the findings may reflect a limitation of the legislation that employees must be employed for at least six months before having the right to request and that not all employees may be aware of their right to request flexible working.

Ms Wilson said: "Many employers may remain sceptical about the benefits of flexible working and under the legislation are able to refuse requests providing they have a valid business reason such as a burden of additional costs, an inability to reorganise work amongst existing staff or a detrimental effect on ability to meet customer demand.

"Barriers such as negative line manager attitudes and a cultural presumption against flexible working in organisations may also exist to dissuade employees from submitting a flexible working application in the first place, and those employees who have applications approved may experience a stigma associated with working flexibly which has been found to lead to limited career progression."

She also found that part-time flexible work continues to be predominantly used by women, with little sign of change.

Women with children under the age of 16 were up to six times more likely than those without dependent children to work part-time.

Men with children under 16 were no more likely than those without dependent children to work part-time.

Flexi-time was more likely among employees in the largest firms, those working in a management role, those in the public sector and those educated to degree level.

Homeworking was less likely in the public sector compared to the private sector. It was also up to three times more likely to be used by those educated to degree level.

The findings were presented at the British Sociological Association conference in Belfast.
