not having a go at your personally mate, but i think that goes for almost any job in the world these days any job with meaning has responsibility and unfortunately a larger work load then the pay cheque reflects but what choice do u have, a real job/career or work a mindless job that requires no over time but gets u nowhere in life either..
like i said dont wna start anything with you but i just think unpaid over time is par for the course now days...
