You will not know how dysfunctional and bad Air Wisconsin is until you leave for greener pastures. I will get chastised by the AW faithful for saying that.

It is a great group of people all in it together but the way that things operate at ZW are just bad. From the union to management inclusive of scheduling and staffing it is not a great place to work.

Great insurance and a great group of pilots, but not a great place to work. This should provide insight to the OP’s question, while also exhibiting the toxic relationship between ZW Alpa and ZW management.

Granted this article is old and ESL is long gone, that was ALPA’s stance on it circa 2014.
