If an employee refuses to wear a face mask at work, can I discipline or dismiss them?

In appropriate cases, disciplinary action and then dismissal may be fair if an employee refuses to wear a face covering in the workplace. For example, if this is in breach of the government guidance or if  employer has issued a reasonable management instruction to this effect due to an identified health and safety risk.

It is important that employers use a fair and reasonable procedure when deciding whether to discipline and/or dismiss an employee and that its actions does not unlawfully discriminate against employees who have legitimate reasons for not wearing masks, such as those individuals who have health conditions like asthma.
