If employees are off work for 7 days or less, they do not need to give their employer a fit note or other proof of sickness from a healthcare professional.
When they return to work, their employer can ask them to confirm they’ve been off sick. This is called ‘self-certification’. The employer and employee will agree on how the employee should do this. They might need to fill in a form or send details of their sick leave by email.
Please follow this link to complete a 'self-certification' form https://www.gov.uk/guidance/ask-your-employer-for-statutory-sick-pay
