In a couple of post s before someone said that he was called up to management to explain his delays even though the reason was technical. This kind of pressure must be put aside, because when something happens you can't defend yourself on those unwritten rules. The finest example is exactly this one. By trying to be friendly to his colleagues and to the company, this captain just lost his job. However, I find it very hard to get a kick on the butt when you have a sound reason to delay a departure, for example.
So, my two cents are, safety is paramount and no bean counter is willing to face in court by firing you for putting safety issues in front of commercial reasons.
