When determining how employees should give notice when they are sick, there are two main points to consider:
the employer can via a policy (written or verbal) regulate the nature of the notice to be given e.g. the employee has to speak (not text or email) to the HR manager before 8.30am;
it makes sense for the policy to require the employee taking leave to have to speak to a person in management. Such a requirement generally is not unreasonable and will not prevent an employee whom is genuinely unfit for work, or required to provide care or support to a member of his or her immediate family or household, from making such contact and providing notice.
