I work 8hrs a day and willing to work more and on holidays.
Obviously, no one wants to work more than they have to, we still all want a life outside of work. But I understand that if I want to get somewhere in my career, there will be days, months and years that I will be working more than just 9-5 Monday through Friday. If a project deadline is approaching I have no difficulty working longer hours or even weekends. I know that if I do not meet the deadlines, it would be much worse for me so I do not expect myself to miss a deadline.
8 but I am willing to work more hours if it is needed.
