I came home today and though about his suggestion. It does have some merit.
- Sick days are stricter to obtained, and needs to be backed up with some documentation like a doctor's certificate.
- You have the freedom to do whatever you want on your Annual Leave Days, but on your Sick Days, you are only allow to recover from your illness.
- When you depart from your job, your Annual Leave Days are worth more and than your Sick Days, so it is worth more in your pocket.
