You can't cheat economics, as said before it's simple supply and demand.
Whether you decide to save everyone's job or whether you decide to job share terms and conditions will come down.
Now for a few, these terms and conditions in the future will eventually come back to some a degree or another.
But for the masses I don't believe as a pilot you will see great terms for a very long time.
There will be a mass load of pilots on the market, and very few jobs to go around. Furthermore this virus won't just disappear, no drugs are significantly working and vaccine is months / years off, which means with reduced travel, holidays abroad there is probably still a good chance of other airlines still going bust, leaving even more pilots unemployed.
Now born out of every crisis there is likey to be new startup companies to suck up pilots / crew etc. But these startup companies are more likely to follow a Ryanair type of employment, whereby you will be on a zero hour contract, and have to pay for training. And there will be an abundance of pilots signing up to these daft contracts a, ready to shaft one another to see how low they can go. Let's face it, they were doing it in the good times, so they are certainly going to do it in the bad times!
Also soon as there is a glimmer of hope on the horozion of improvement in the job market, your likely to see mentored pilot schemes starting to pop up. Why because it is a fantastic revenue source for training organisations and the airlines. When this improvement happens will these newbie pilots be required, I would say not due to the surplus of pilots on the market, but these schemes will still go ahead, wherby a pilot who is unemployed, will loose a potential job to a newbie, who is strictly probably not required at that time.
If future pilots can not get an employment contract or their training paid what hope have you got for proper terms and conditions in the future.
In order to change things the supply needs to be changed. As I said before one way to change the supply is change hrs required to fly a jet, hrs to become captain, increase age to fly passengers etc. The other thing that's needs to be done is stop these zero hour contracts. If these were stopped there would more of a level playing field wherby other pilots can not undercut other pilots by signing up to dodgy companies.
That said for these things to change, there has to be a change in the law / regulations and I doubt very much that will happen hence why there will not be an improvement in working conditions.
