I am working for a company for the last 6 years. I was hospitalized and am currently receiving medical treatment. I am in need of leave for medical purposes. Although my accumulated sick leave days are over, I have more than 90 days of paid leave available. I have applied for leave and requested that my paid leave be adjusted accordingly. However, HR is stating that it will be unpaid leave. Please advise when earned leave is available in my account, how can the company deny adjusting my paid leave and place me on unpaid leave? Please advise if there is any law or clause under labor laws that supports this decision.
