The figure of 97% is brought up time and time again. 97% is one hell of a huge majority........Think why. Because 97% of engineers are not stupid! By voting to opt out it gives the individual a choice to work long hours or to only work a standard shift. An employer can only ask, not force an employee to work excessive hours. The choice is therefore yours and you have the freedom to make the decision yourself rather than be regulated. Nice position to be in!
