On 3/3/2020, ACAS published a very useful guide about handling coronavirus at work, an extract is below":
" In case coronavirus (COVID-19) spreads more widely in the UK, employers should consider some simple steps to help protect the health and safety of staff.
It's good practice for employers to:
Employers must not single anyone out. For example, they must not treat an employee differently because of their race or ethnicity.
The workplace's usual sick leave and pay entitlements apply if someone has coronavirus.
Employees should let their employer know as soon as possible if they're not able to go to work.
The government has made clear that if NHS 111 or a doctor advises an employee or worker to self-isolate, they’re entitled to statutory sick pay. If the employer offers contractual sick pay, it’s good practice to provide this.
The employer might need to be flexible if they require evidence from the employee or worker. For example, someone might not be able to provide a sick note if they've been told to self-isolate for 14 days.
The employee must tell their employer as soon as possible if they cannot work. It's helpful to let the employer know the reason and how long they are likely to be off for."
