It’s all about the money/roster/leave and secondary benefits like pensions, loss of income/license insurance, medical insurance. And having these things in the contract does help so the company can’t just do what they want when they so require.
And that’s the entire issue, WZZ is unfortunately inadequate on all fronts as a long term employer. In a crisis market with a surplus of pilots it’s not an issue as people will take opportunities to gain experience on a medium jet. But with the market we are in now this is only going to end in disaster eventually.
I have worked there for close to a 4 year period and have flown with serious operators out of GDN. Don’t recognize the poor training statements by CAK.
