A coalition of 18 unions has called on NHS leaders to make flexible working the norm in order to deliver better care and resolve the staffing crisis.

The group has launched a new initiative to promote more choice for staff over how, when and where they work.

The Get Ahead on Flex pledge urges employers to speed up their progress on working arrangements that allow more freedom, including team-rostering and 'any-hours' contracts.

Those who sign up to the pledge will commit o highlighting flexible working in every job advert, setting targets to increase the number of requests approved, publish data and train all managers on how to champion choice for workers.

While NHS staff have the right to request flexible working, health unions say it is often difficult to access the flexibility, with inconsistency across employers leading to a postcode lottery.

Chair of the NHS unions and UNISON head of health Helga Pile said: “Too many NHS staff are struggling to balance work with other parts of their life including caring commitments. This affects their health and well-being, and forces many to consider jobs elsewhere.

“The NHS has long talked about the importance of improving flexible working options. However, old-fashioned attitudes and rigid one-size-fits all shift patterns are still getting in the way.

“This pledge provides a real opportunity to improve working life for staff and give patients a better service.”

Campaign lead for the NHS unions on flexible working and Society of Radiographers head of industrial relations Leandre Archer said: “Flexible working shouldn’t depend on which employer you work for or who your manager happens to be.

“NHS staff deserve fair, consistent access to flexibility so they can deliver the best possible care without sacrificing their own wellbeing.

“The Get Ahead on Flex pledge is a vital step towards ending the postcode lottery and making flexible working a genuine reality across the NHS.”
