Top executives at Yorkshire Ambulance Service have been awarded pay rises of up to 30 per cent.
Latest figures show that chief executive David Whiting saw his salary rise nearly 10 per cent to £141,000 in 2013-14.
Finance and performance director Rod Barnes saw his pay go up from between £95,000 and £100,000 to £115-£120,000, while director of standards and compliance Steve Page saw his rise from £85-90,000 to £110-115,000, an increase of at least 28 per cent.
Around half the staff at the ambulance service earned less than £21,400 last year.
Interim director of workforce and strategy Nick Cooke, earned between £55,000 and £60,000 for three months’ work last summer.
Michael Fox-Davies, interim director of operations, picked up £115,000-£120,000 between July and December.
Yorkshire Ambulance Service NHS Trust, which employes more than 4,600 people, said executive salaries had been reviewed because of higher-than-average turnover and difficulties in recruitment.
An independent advisor found previous salaries were at the “bottom end” of NHS salary scales.
An ambulance service spokeswoman said: “In addition, some executive roles have increased portfolios of responsibility such as the new NHS 111 urgent care service launched in 2013.”
