Hi. The company I work for recently introduced a Company Policy which all of the employees signed, in it, it states that a Medical Certificate must be supplied regardless of the number of sick days taken as sick leave. One of the employees has taken a sick day and did not bring in a Medical Certificate. Can the employer refuse to pay him for that day, either out of sick leave entitlements or annual leave entitlements? The day would in effect become a LWOP. What are the employers legal obligations to the employee under employment law?
