Stress. Its what us pilots try real hard to give to you. We thought you liked it.
We have a number of ways of increasing this magic thing called stress. Below are some examples.
1. Don't be available on the mobile when we said we would and we are on standby
2. When you do get through to us moan like hell and spend the next 10 minutes arguing about how we can get out of the duty
3. When we have to accept the duty find 27 reasons why we a) need another day off b) are out of hours or c) can't do the next 5 duties
4. Divert to another airport (for any reason you like)
5. Break the aircraft enough to cause a delay
6. Break the aircraft enough to cause a diversion
7. Break the aircraft enough to get a nice little nightstop followed by a day or two somewhere hot (our favourite, and something we try really hard for, but only works a couple of times a year we find, or you lot get suspicious).
8. Calling you to tell you we are not going to that crap diversion that is listed on our plog, but to another one, further away, where you have no personnel to deal with the punters (and oh dear, I can't quite hear you now on the HF, we'll talk to you on the ground)
9. Do a runner before said punters realise they are stranded for 3 days with no-one that speaks English
And YOU complain!
