What I would like to know, does Atlas tell their job candidates that accepting a job at SAI means that their pay will be a small fraction of what they would be paid at Atlas?

That the environment, working rules & conditions at SAI are WORSE than Atlas? That it will NEVER get better, and it is Atlas management's intention to keep SAI as the PERMANENT under-class of the Atlas organization.

Do they show you both CBA's prior to hiring you, or do they just give a job offer based on their "good faith"?
