BBC reports that in 2014 the number of hospital staff off sick due to anxiety, stress and depression is significantly high, doubling the figures for 2010.
A spokesman for NHS admits that NHS needs to improve the support it gives to the staff, "not least because better staff experience leads to better patient care".
Tim Baggs, from the Royal College of Nursing, says the figures are in line with the data they have been gathering over the years on the high levels of stress NHS staff are under.
Emma Mamo, from mental health charity Mind, says absence due to mental health issues will keep rising as a result of funding cuts to NHS services, leading to the loss of a considerable number of positions and higher workload for existing staff.
