//saying that secretares "answer the phone and do a bit of filing" is just as ignorant as saying lorry drivers have it cushy//
Indeed it is. I was being flippant. So since you've picked up on it, let's be a bit more realistic: what would you consider the most demanding job (for £30k p.a.):
As an HGV driver, slogging up and down the country for twelve hours a day, stuck in traffic, coping with driving a 40 ton lorry in all weathers, eating in greasy spoons, sleeping in your cab for five or six nights a week, undergoing 35 hours of compulsory training every five years in order to renew your licence, running the risk of losing your job if you make a minor mistake and cause an accident
or...
Working in a comfortable office 9am-5pm five days a week, having an hour for lunch, possibly at an agreeable cafe or wine bar or perhaps doing a bit of shopping, having a coffee whenever you fancy one, undertaking some administrative tasks, facing just a mild admonishment if you make the odd error.
Well???
