People are now no longer being advised to work from home, but employers should give extra consideration to people at higher risk and those facing mental/physical health problems. While people who previously needed too are no longer being told to shield, employers should talk to the individuals about their needs and provide them with the support they need. As part of your risk assessment, you should have identified employees that are more at risk of Covid-19.
It is of utmost importance that you have open lines of communication with your employees and discuss any concerns they may have. It may be possible to redeploy them into another area in the business which will result in less human contact or allow them to work from home. It may be that they can still be furloughed, as the initial shielding period was set as 12 weeks. Continue to follow the current government advice on shielding.
