It is common sense to do a risk assessment of returning, and you will be fully aware that many businesses have felt enforcing everyone has been vaccinated will reduce any potential claims or issues resulting from employees becoming ill.
Many businesses are worried that if they do not enforce everyone having vaccinations before returning to an office, that they may be liable if an employee returns, has covid, infects a person or, persons. In the worse case scenario of an employee dying because they contracted covid from a colleague whilst at work, the company could very well be liable under health and safety at work.
