But, of course, businesses face other legal hurdles. They also have privacy law. It's not clear if they are able to address the issues with privacy. So that's a real problem. This legislation, in fairness, does set out the use of vaccination data and any information about vaccination that an employer might have and how they can and can't use it. So that's a big tick. It also offers to have a framework or a tool that businesses can use to work out what their real risk to each employee is of COVID so they can work out if a requirement for that person to be vaccinated is necessary to fulfil their health and safety rules. There's also a conflict between the health and safety rules and employment law, because it's possible to say that a new employee must be vaccinated—if that's your business and that's your rules, you can do that. It's a very conflicted situation for a business that wants an existing employee to be vaccinated. It's not in their employment contract, they don't necessarily have to be vaccinated to continue working. So that puts employers in a very difficult space.
