TRADE unions face a looming dilemma over whether to support workers who refuse Covid jags and so clash with their employers and colleagues, a leading public health expert has warned. Andrew Watterson, professor of occupational and environmental health at Stirling University, said unions had so far been urging vaccination take-up, and for making key workers a priority. But as lockdown restrictions ease and working from home ceases to be the norm, the same unions now have to consider how to handle members who refuse vaccine. In a paper published in today’s Scottish Left Review, Prof Watterson was also critical of how the vaccination programme had been rolled out in Scotland and the rest of the UK to key workers.
