By all means go on strike
Great Idea
Two things will happen.
RYR will use its extra capacity to mop up the extra pax and make loads of money in the meantime.
Many pilots will see that their homes and famillies and incomes are more important and the strike even if voted for, will fizzle out as people turn up for work, rather than put their livelyhoods and jobs at risk.
You are fighting a loosing battle to even suggest such actions.
The battle has already been lost, and if you intimidate the cadets under training it will be seen as bullying and subject to instant dismissal.
I suggest that you "Grow Up and Face Facts" the system is in place and will continue as long as the market is pro company.
Wait bide your time and when the tide is in your favour try for the changes you seek.
Bargaining from a position of weakness is foolhardy.
