Ramp doesn't want you to call for push unless the ground crew is in place. Especially when de ice ops are in effect. We never have had this problem at Colgan. In fact a lot of guys I fly with will brief the notams prior to closing the door. Then close door, release break, brief the flight, start engine, then call for push. In fact that's kind of the order the FOM suggests to do it in. Briefing the flight is part of your job.... I don't know about you but I don't work for free!
