Say what you will about BB's management abilities, but after the contract/strike is behind RAH, they will be looking to get back to business as quickly as possible.

Yes - they will likely fire you for not showing up and for not crossing the picket line.
Yes - they will almost certainly take you back immediately after the contract is signed.They have $30K or more wrapped up in you, common sense say they will take you back.

Here is the real question -- when you are directly asked the question on any application or in any interview, "Have you ever been fired from a job?" do you really want to have to do that dance?

Be smart -- Stay away from RAH until this thing is over. Every pilot that goes somewhere else right now is bringing RAH management closer to offering a reasonable contract. The now 5 year expired contract at RAH is one of the many things keeping the industry wages and qol down right now. Do the right thing and apply elsewhere. Going to work at RAH right now is supporting Management and hurting the RAH pilots and this industry.
