Dr David Reid, the committee chairman, said he had been approached in a couple of instances while many more had posted about the issue on his Facebook page.
He said: "It's not a surprise to any of us really. We've known for a long time that junior doctors routinely work more than 100 hours a week. However, I think it shows that we do need to be taking a look at how rotas are put together and who is putting them together. It varies from department to department and while they tend to comply with the letter of the law, the problem is they don't really stick to the spirit of the law."
