I have little work experience (mostly academic), so bear with me. Maybe go to the higher ups with this and tell them that you are willing to put the extra hours in but expect to be compensated? Maybe they'll tell you to go for it maybe they'll tell you to slow down for a while. Either way you get an answer and some rational expectations about the future about your compensation and appreciation as an employee. Lots of negativity and hostility here to the OP btw. Op might do us well to give us some more info (big corp or startup for example?)
