A Healthcare Commission survey found that 73 per cent of NHS trust staff say they have access to flexible working.
The number of staff working for longer than their contracted hours has fallen, from 71 per cent in 2005 to 66 per cent this year.
By contrast, from this month, GPs must work longer hours to qualify for the same funding.
The Healthcare Commission survey also found that less than half of NHS staff felt that patient care was the trusts' top priority.
The survey included more than 150,000 staff from England's 391 NHS trusts.
