AMC requires pilots to show up early to check weather and pre-flight so they are "duty ready" when their shift begins and they are not paid for that time before their shift starts.

From the CBA:

Duty Ready: To facilitate customer and Company needs the oncoming Pilot will be duty ready
at the beginning of their scheduled shift. Duty ready is defined as being available to initiate and
conduct revenue or non-revenue flights. The expectation is that a Pilot will accomplish all
required Federal Aviation Regulation and General Operations Manual actions within the time
period that precedes their duty shift.
