The "being asked to use their personal/sick days" is the reporter's interpretation of having to go to the "My RTO" portal to set their status.
1. If you are able to work from home, set the proper code to avoid losing PSSL days 2. If you aren’t able to work, you need to use a PSSL day.
What’s not fully clear to me is whether the expectation is normally that you work on a PSSL day, as it seems to be the case that you get paid on those days whether you work or not.
