More Welsh Ambulance Service staff off with stress

A growing number of ambulance service staff are going off sick due to stress, BBC Wales has learned.
Their sickness rate of 7.53% is the highest in the Welsh NHS and almost double that of the police which is 4%.
Since May 2013 the service has only once hit the 65% target for reaching life-threatening calls within eight minutes.
Bosses admit that ambulance queues outside A&E could get worse with hospital reorganisation unless more staff are hired.
