We have an employee who requested 1-day sick leave after having a mole removed from their face. We are a building company and did not have any work that week so we requested that the employee take the rest of the week off from accumulated RDO's after the sick day (3 x RDO's). The following week the employee sent us their hours with a medical certificate for 3 sick days instead of the RDOs. We paid that after discussing the case with his doctor - who stated that there was a risk of infection so the extra days were warranted. The following week, we had no work and asked him to take a week's annual leave (he has 5 weeks accrued). When we received the next week's email from him, they sent a doctors certificate for another 5 days. Is this legal and how can this be challenged? Do we just have to suck it up and pay him? Should we get another doctor's advice as to whether he was entitled to the 8 days work to have a mole removed? Redundancy plus his leave. He is just trying to play the system and our business for whatever he can get. What should we do? This all seems very unfair but not sure where to go for help.
