hi guys, i am under the MX scheme and have a question about entitlements here.

My off day is on a weekday because i am working on saturdays for full day.
I have a department retreat on my weekday off day and i am not compensated OIL.
If i am sick for my department retreat, do i need to take MC and apply sick leave in the HRP employee system?

Cause my Director, Deputy Director and Assistant Director all told me to take medical leave for my off day and i just want to check my rights.
