Pilots only are about number 1, and only ever look short term.
That's why Aeropelican then Brindy's went down this path - pilots would make an undertaking to stay for a return of service obligation and then (almost immediately) update their application with Virgin or Eastern or Jetstar.
As soon as they were offered an interview, they buggered off. Some of these pilots joined without 500 multi and were ICUS-ed up (at considerable expense) to meet command requirements.
If no pilot had ever renegged on a ROSO, we would not have this situation where businesses have to take steps to protect the investment they made in your training. It's a two-way street
