Learn to differentiate fake vs real sickness. Even fake MC once a month is considered as very good already. I used to have a colleague that MC 4/5 days per week. Once we are over 30 years old, our body is more prone to sickness (myself is example), especially when under stress (deadline, issues, etc). To me MC is not an issue, but IF it's an abuse of MC, then the pattern needs to be studied before any action is taken. This is to prevent penalizing those who really needs it. HR needs to clarify in front of everyone that MC is not annual leave (must clear all). It's only meant for sickness.
