A growing body of evidence suggests that inflexible working is pushing parents out of jobs and into difficult financial trade-offs, with fresh polling showing that more than a third of workers with children under seven have left a role because it would not fit around childcare.

Lack of flexibility affects recruitment as well as retention

The Opinium survey, highlighted by The Independent and echoed in a separate TUC briefing, found that 30% of parents with young children had seen informal requests for flexibility refused, either wholly or partly. More than half of prospective applicants said they were less likely to apply for a post if they could not tell whether the hours or location would suit their lives, underlining how employers’ recruitment practices can narrow the pool before interviews even begin.

Trade unions call for stronger action

The TUC says that is not just a family issue but a labour-market one. General secretary Paul Nowak argued that flexible working is "a lifeline for working families", adding that rigid workplace culture is still excluding parents from jobs and harming retention. The union wants ministers to go further than existing reforms by requiring employers to advertise whether roles can be done flexibly.

Research highlights the scale of the problem

That concern is shared by the Chartered Institute of Personnel and Development, which says around 4 million UK employees have changed careers because of a lack of flexibility. The Nuffield Foundation has also warned that one in three flexible working requests are rejected, while many mothers end up sacrificing pay or promotion prospects to secure the arrangements they need.

Lower earners face greater barriers to flexibility

The issue is especially acute for lower earners. The TUC has separately said that 53% of new fathers and partners who asked for flexibility did not get what they requested, with rejection rates even higher among those earning under £40,000. A wider survey cited alongside the flexible working research suggests that workers are already under pressure from rising living costs, making it harder to absorb the loss of income that can come with leaving a job or reducing hours.

Flexible working increasingly seen as a necessity

For campaigners, the case is becoming clearer: flexible working is no longer a benefit to be granted selectively, but a basic condition for keeping parents, and others with caring responsibilities, in work. They argue that businesses which fail to adapt risk losing experienced staff at a time when recruitment remains difficult and skills shortages persist.

Reward Strategy Says

The latest research reinforces the growing business case for flexible working as both a retention and recruitment tool. With surveys suggesting that a significant proportion of parents have left roles due to inflexible working arrangements, uncertainty over working patterns is deterring potential applicants before they even apply. With evidence indicating that lower-paid workers face greater barriers to securing flexibility, employers may face increased turnover, recruitment costs and workforce planning challenges if flexible options are not readily available. As policymakers and unions continue to push for stronger flexible working rights, organisations should review their policies, reward strategies and workforce practices to ensure they remain competitive in attracting and retaining talent, particularly among employees with caring responsibilities. Flexibility is losing its title as a benefit, and gaining one as an expectation.
