If you are training people and they aren’t staying, isn’t the implication that you aren’t paying them enough? Those union apprenticeships are often hard to come by because 1) they pay quite well compared to other viable options and 2) people don't want to leave because of #1. If the job is demanding, the pay should be commensurate. The exception is if it’s rewarding on some other axis (e.g., socially).
