I do not think that there is any need to add to that observation.
When people work on a regular basis, that has to be accepted and provided for. That is what amendment 10 would do. If somebody genuinely does not want a permanent contract, nobody is saying that it should be forced on them. Amendment 10 says that people should be offered such a contract. If there really are all those people out there who would not want a permanent contract instead—I have to say that I doubt it—they would, of course, be free to turn it down.
