You are leaving stuff out. You call crew tracking who then tranfers you to a duty pilot where you have to repeat yourself. Then you have to fill out fatigue form where you pit everything you said in writing. Then chief pilot follows up the next business day where you have to repeat yourself all over again. In my experience, the chief pilot threatens to not pay protect you as intimidation. In my case there was nothing to pay protect me for which is why I took it as intimidation. Most guys here like their job and extending is just easier as it is what our company expects you to do.
