Doctor bookef her off sick but the company decided not to pay her pay supposed to earn which ended om her accounts not being paid.She was told to come to work even if she is still on crutches so as company could claim for compensation.Injury on duty was completed by manager/supervisor instea of safety officer (no safety officer at that company. She is even working using crutches with no payment. She has to go to loan sharks to make ends meet.For this mpnth she wprkef fpr almost the whole month but still unpaod.She tried contacting hr who also coudnt help of which at wages she was told to fill in forms for leave to be paid which is not possible for employee with injury on duty.She even has to pay transport for doctors appointment.All required doctors letters were submitted to the company but nothing helped.labour law seems to be ignored as per above statement.
