The pre 10am contract language drives premium pay every summer, holiday, and bad weather day and instead of paying a senior pilot 20hrs of double time on a 4 day they want to give that flying to a reserve for 2 hrs of add pay. You are only a reserve for a few years but currently every lineholder has a shot at premium pay. Seniority abrogated in a very big way with this and a huge change from past practice. It will decimate premium pay and force senior first officers making 200-300% every month to upgrade. That is my biggest gripe so far, plus pricier health insurance, and a lack of QOL improvements. Not good.
