During the coronavirus (COVID-19) outbreak, the government has defined some people as clinically extremely vulnerable (shielded). Shielded workers are at increased risk of severe illness from coronavirus. As an employer, you have a legal duty to protect workers from harm. You should make sure you consider the risk to workers who are particularly vulnerable to coronavirus and put controls in place to reduce that risk.
