Just an opinion, no facts or rumors.
But if I was in the pool here at ExpressJet I would be going to Eagle or Republic. Those places have reasons to hire (attrition due to flow or new contracts) we do not. We have very little attrition and being all of our employees are paid "ok" and not miserably like other places it is harder for us to get new flying due to total costs and how senior ALL departments are compared to other places (pilot costs are a lot less of a factor than these boards portray them to be, so yes ALL of our departments). So your QOL here will not improve quickly until all majors start hiring more than the little they are. Also, why not enjoy the $5,000 bonus to help through first year that both of those airlines offer. We don't offer it here because we have very little attrition so very little need to be hired. Go to those other places and enjoy a descent schedule with a little less pay over your next couple years.

Personally I think they are telling you guys March just to keep you from running to other places. We shall see if my guess is correct over the next couple months.
