An employer can call an employee who is off sick. How often this can be done will depend on the position of the employee, the provisions of the employment contract and the culture of the organisation. For example, a senior manager who is off sick may still be required to answer reasonable questions about his workload in his absence to allow for others to take on his work. Employment contracts usually mandate communication between the employee and the employer during sick leave. This is usually to establish how long the employee will be absent from work. Any contact made with a sick employee should be reasonable.
