Can't say I've really had too much negative reaction in fairness - like some other posters have said, in my experience it often seems to end up with morbid curiosity asking about fatalities and actually quite sympathetic. On the odd occasion where a mention of the "always on strike" line has come up, if they're someone else local I simply ask them when the last one was and then, after they've had a think, remind them that the most recent driver's strike dates announced locally were getting on for two decades ago... and they got called off!

The line about pay I usually just suggest they apply, which usually ends in them admitting they don't want to be getting up (or getting home!) at 3am, and working two or three weekends a month...
What always confuddles them is when trying to arrange something and they ask "What are you working Saturday?" and you have to try and explain you don't know yet as you are 0730 "spare" on the base roster so won't know until around day and a bit before - so you might find you are working 0530-1500 so free in the afternoon/evening, but you might also be working 0930-1900... or anywhere in between!
