What can I do if an employee refuses to work due to lack of PPE?

Put simply, if it is a requirement of a particular role that PPE is worn, then this should be provided to the employee. If an employer dismissed an employee for refusal to carry out their role due to lack of PPE then this is likely to be an automatically unfair health and safety dismissal.

Furthermore, anyone who is subject to a detriment as a result of raising a health and safety concern, e.g. someone in this situation who refuses to work due to lack of PPE and is sent home without pay, will also have a potentially valid claim in the Employment Tribunal for that detriment, even if they are not dismissed.
