I don't believe there is anything in writing to say "compulsory" but if you ask anyone who has started with McDonald's, they will tell you it is made pretty clear it is not an option. McDonalds makes it very clear to everyone, including the press, that the FDA is their partner in this and they are working together. There was a number of presentations to FWA regarding the "understanding" between McDonalds and SDA. I did have some details when we working through some FWA stuff for a client. There was a lot of complaints at an ALP conference because the McDonald/Woolies/Coles deals and their compulsory membership gave them a huge increase in numbers and that votes in the ALP were at a ration of union numbers.
