I think so... I heard a couple people that went to those two companies, and some that have gone to the majors over the past 2-3 years... the new contract isn't so bad either and is actually very competitive, considering the CVG location... I'm sure the next contract will just get better... if someone ends up staying there for the next 3-4 years, they might end up just staying there for the rest of their career and it wouldn't be so bad I'm sure...
as far as the Polar side itself, it's mostly DHL flying so very little ad-hoc or supplemental; unlike Atlas... but still extensive international, ETOPS, and widebody experience... they tend to run the staffing on the low side (only 1 being hired right now), most shifts have 2 people on them but if one calls in sick, you're SOL unless they find someone that can work OT... i know the people that work on that side tend to like it though... with a relatively lower number of dispatchers, going up in seniority is easier, plus the opportunities for OT shifts (if you're into that) are widely present...
