If you happen to be assigned a DP on Reserve which should be the ONLY way you are flying a DP (or you're an absolute douche), and if you recongize fatigue creeping in, it is the perfect opportunity for a fatigue call - don't waste it. That is the only way those pairings get fixed.

We fly some of the most onerous pairings in the industry, yet have one of the lowest rates of fatigue calls. Why is that? Because for decades we have chosen to power through those pairings to make it happen for a company that had our backs for the most part. But not the new corp. They will bid out our flying to cheaper labor, to legally and efficiently outsource as many of our jobs as they can going forward.

Many guys don't know that they're picking up a DP. Get educated. If you have friends picking them up, do them a favor and tell them why it hurts all of us. If you're on RES and get one assigned, do NOT power through if you feel fatigued. Call it in.
