That is an important comment, and it illustrates again the importance of giving people protection that they do not necessarily have at the moment. In a lot of situations, the employee is perforce in a much weaker position than the employer.
I fully accept that there can be circumstances in which people can find contracts such as we are discussing a useful way to live their lives, provided that they have equal bargaining power. I remain slightly unclear, however, about why people who want choice would not on the whole be better operating on a self-employed basis. There are a lot of people who have been doing regular work and who everybody knows are employees, but who cannot easily get permanent work. Some employers might find it difficult to rearrange their planning to let them have a permanent arrangement, but things seemed to operate on that basis for many years. I cannot understand why it has suddenly become so difficult for employers to manage.
