Jeremy Hunt’s staff have taken double the amount of sick leave than the average person.
People working at the Department of Health have taken more than 50,000 days off for sickness in the last three years.
Sources have reportedly claimed the leave is due to stress and anxiety, sparked in part by unprecedented cuts.
DoH civil servants took an average of eight sick days a year between 2014 and 2016.
According to the Office for National Statistics, the national average is four.
The news comes amid one of the worst NHS crises in recent history, with tens of thousands of operations cancelled across the country.
A Freedom of Information request, published by The Mirror, found that DoH staff called in sick a total of 50,037 times.
It also revealed that the total number of employees had been cut from around 2,000 to 1,650.
A DoH source told the paper: ‘Many staff felt they were bullied, or at least strongly encouraged, to accept voluntary severance.
‘The alternative was to apply for one of the remaining posts, but many staff were informally told that they would not be successful and so should accept early severance.
‘This was very unsettling with management behaving very aggressively.’
