The online survey of 19,000 staff – the first in the NHS to focus purely on the health and wellbeing of employees – was developed by NHS Discounts.
According to the report, more than a third of NHS staff admit to work-related stress in the past 12 months. And one in five believe their job is bad for their health.
The survey, conducted before the two-year public-sector pay freeze announced in the Budget, reveals 60% of respondents are already trying to generate additional income, cutting back on spending, working extra hours or taking on another job.
Donna Bradshaw, joint managing director of change management consultancy ODS, said: "This survey contains some strong messages for the NHS to think about and act upon in terms of health and wellbeing at work.
"Staff admit they are putting themselves under pressure to come into work when they are not well enough, suggesting there is a huge amount of loyalty and a strong work ethos; but this must also raise questions about the safety of doing so.
"Stress is a key issue for NHS trusts to consider and given the looming public-sector cuts, there is a risk that stress-related absences or even errors at work may increase.
"The survey also contained some good news. Line managers, counselling and occupational health services play a crucial role in supporting staff and helping them achieve a work-life balance. Trusts need to ensure that line managers feel informed and equipped to promote wellbeing and are able to recognise and address the impact of and risks associated with staff working while unwell or under stress."
