Basically mate - it's the U.S. way of working too, if she shows she's prepared to throw her all in to it, working all hours god sends, that will go down very well indeed - especially in a manager position, she'll never get a minute to herself.
They love the word flexibility - which basically means you do everything they want, when they want it.
I regually get mails from my manager at 10 - 11 at night on most days, she tells me she does 15 hour days easily and I can believe it.....oh andmanagers can't cliam cash back for those hours either. I can
Who wants to be a gaffer eh! Quite happy fetching the tea......
