Name an established airline with good terms and conditions, which has an ab initio training program in place and is experiencing a shortage of Pilots.
Even without a cadet program, the top tier can still crew their aircraft. There may be bottle necks in training and the net may need to be cast a bit wider with reduced minimums but they can still get by.
Shortages are primarily with:
Rapidly expanding airlines in China and Asia whose growth has outpaced the normal lead time from off the street to experienced Captain.
Previously top expat employers such as Emirates and Cathay who let their terms and conditions slide. Now a job back home is a more attractive option.
Second level airlines such as Ryanair who screwed their Pilots into the ground during previous surpluses.
Regional and general aviation level jobs which have traditionally paid poorly and simply been regarded as a steppingstone to better things. Their Pilots have moved up the food chain and haven’t been replaced.
