The answer is yes - on regular occasions over a 4 years period I did, we famously worked 7x12 hours on night shifts and were supposed to have a week off after that but it never worked out that way. It was the same for the doctors we worked with. Sickness absence through stress was very high in A&E and given the choice you would do the extra hours because you didn't know if you would need the extra bodies yourself the following week. They (the Drs) were protected by derogation, we weren't - but it happened - and like a lot of things in the NHS it was kept very quiet until matters improved and we got more staff.
I can't imagine we were that unusual, I expect it happened a lot in London hospitals where attracting staff is an issue. Although what their stance was/is on WTD I cannot say.
As for my husband, well I believe in freedom of speech as I know you do too so I defend his right to his opinion and as I am an independent sort of woman I am using my own machine
