Sounds like management doesn't appreciate you, nor are they competent at what they do. You deserve better. It's commendable and professional to work a set number of hours (~7-8 / day, though it varies). It is unprofessional and a sign of management's failure to ask you to work more, work on weekends, or catch up to hours you don't owe them. It would also be unprofessional for you to bow down to such ridiculous requests. It sounds like you are contributing more than anyone and with your skill-set, you should have no problem finding another job, hopefully one that isn't filled with unprofessional managers who can't manage and demand one work unprofessional hours. tl;dr: Working more than 8 hours a day is unprofessional (except in rare, extreme circumstances where it is rewarded).
