well I thought I'd actually post something and here seems to be as good as anywhere!!!
I work very hard for about 10-15 days a month and then do squat for the rest of the month. That said I have recently got back on my bike after 3-4 years off it and my doing squat time is fast becoming consumed with riding fixing and shopping
My 10 – 15 days a month are usually 20+ hour days and have strict deadlines like a production manager, and artist and an audience expecting that if doors open at 7.30, doors will actually open at 7.30 and there will be something resembling a lit stage behind those doors.
I generally see it that those higher up don't necessarily work harder, they just stand closer to the fan that the proverbial may hit!
