TBH I don't really understand why they can't just have doctors who do shifts at the GP's on Saturday and Sunday - they don't have to be the same doctors who are there during the week. As well as dealing with people who are ill at the weekend, lots of people who work would find it a lot easier if they could make appointments to see someone at the weekend when they're not at work rather than having to take time off. I guess it's just a question of money to pay their salaries.
