Generally, I will leave the office at around 7pm if I'm staffed on a project. If we're leading up to a milestone or presentation, I will work late nights and/or some weekends. In these instances, I find that people are really understanding and appreciative. Another aspect of the culture that I really appreciate is the lack of presentism so if people have finished early, they are free and encouraged to go home. Relative to other consulting firms and other "intensive" professional service firms I would say that PJP is well compensated for the hours we work.
