ONLY one in five NHS staff members believe change is well- managed, according to a new report.
However, 90 per cent of workers believe their needs to be change in the organisation.
The figures form part of the first staff satisfaction survey since 2007, which was published by the Welsh Government today.
More than 22,000 members of staff in the NHS in Wales responded — but that's only 27 per cent of the workforce.
Key points included: only one in 10 members of staff disagreed with the need for change; more than eight in 10 staff say they are happy to go the extra mile at work and more than eight in 10 feel their role makes a difference to patients; and the majority of staff would be happy to recommend the standard of care provided by their organisation.
David Sissling, chief executive of NHS Wales, added: "I want to thank staff who took the time to respond to the survey. It confirms, above all else, the professionalism and commitment of our staff. There are many encouraging findings, but also areas where NHS organisations will have to work to address the issues raised.
"I am looking to all NHS organisations to listen carefully and respond to the key messages in the survey. These will allow us to build on the positives and address areas of concern — for example about stress and workload.
"Perhaps the most important area that NHS organisations need to look at is changing their culture. At the heart of this will be better staff engagement. The best performing organisations are the ones that actively involve and engage all their staff.
"I expect each health board and trust to put in place an action plan to address the specific findings from their organisation."
Following the survey, Welsh Health Minister Mark Drakeford said the staff were the NHS's biggest asset.
He also welcomed the staff's overall need for change.
"Shining through the survey results is the dedication and commitment of staff to go the extra mile in caring for their patients," he said.
"It is also encouraging that the majority of staff recognise that change in their organisation is necessary — it means that those at the coalface recognise that the NHS cannot stand still if it wants to improve.
"However, the finding that only one in five believes change is well-managed shows the NHS has some work to do to involve staff more in decision-making processes."
