As an employer, you’re responsible for the health and safety of your employees. You must assess and manage the risks your staff will face when returning to work. This includes the risk of contracting Coronavirus.
Before asking your employees to return, you should:
deep clean the premises
perform a health and safety assessment and/or risk assessment to determine what potential risks there are in the physical workplace
assess whether any adjustments need to be made before re-opening to maintain social distancing and personal hygiene, implement flexible workforce arrangements, and to accommodate those with protected characteristics
update your health and safety policy to include Coronavirus-related safety measures
