I worked for a company where the product manager asked me to work into the evening to meet another deadline which he mismanaged (and which I flagged weeks before). He was met with a firm no (which ensued some very strange plaintive messages from his side). I resigned about a month later. I'm of the opinion that perpetually mismanaging deadlines, not only shows a lack of expertise - but also a complete lack of professionalism (in regards to the greater team).
