I think most engineers are in a similar position to those above. Sometimes we are our own worst enemies by working excessive amounts of overtime and accepting shift patterns that do not give adequate rest periods, I know some guys that happily work 19 days on the trot without a day off (normal shift plus otime), you can't tell me that this is safe or healthy. Management are happy because no laws have been broken and otime is cheaper than employing the proper number of engineers. The only thing that will change this industry wide is to have laws introduced that limit duty hours - same as the pilots, I know ours aren't overworked. This would ensure that management would now be more accountable than under the present system of control (AWN47).
