JUST over half of NHS employees said that if a friend or relative needed treatment, they would be happy with the standard of care provided by their organisation.
This year's NHS Wales staff satisfaction survey also showed that more workers disagree (55 per cent) than agree (26 per cent) that there are enough staff for them to do their job properly.
Other 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.
The survey showed that only 52 per cent of employees would be happy with the standard of care for family or friends.
Health Minister Mark Drakeford praised the staff and their recognition of the need for change. He described staff as an the organisation's biggest asset.
He added: "The survey's findings also make clear that there are a number of areas where we need to improve."
And NHS Wales chief executive David Sissling said health boards were expected to put plans in place to address the findings.
However, opposition AMs have voiced concerns following the publication of the results.
Darren Millar, Conservative shadow health minister, said cuts to NHS funding meant it was creating a strain on the service, making it more and more difficult to "provide a first-class service".
He added:"It is deeply worrying that nearly half of NHS staff surveyed would not be happy for their family or friends to receive the standards of are currently on offer in the Welsh NHS."
Lib Dem leader Kirsty Williams added: "We are increasingly seeing the health service in Wales fall behind the rest of the UK. That is far from good enough."
