It is probably safest to assume that Long Covid could be within the definition of a disability when making workplace decisions and to act accordingly. In most cases this will mean:
Consulting with the individual about the effects of the illness;
Seeking appropriate medical advice either from the employee’s own GP or an independent clinician;
Ensure managers are trained in the sickness absence policies and how these related to absences which could arise from a condition which is a disability; and
Be prepared to consider appropriate adjustments to accommodate the effects of the condition if it is a disability.
