Interesting. When I do not feel up to the task of working, whether it is a physical, mental, emotional, spiritual, or arbitrary cause, I use one of my provided PTO days and email the team a short "I will not be showing up to work today" message, without explaining the cause.
I similarly don't bat an eye when a coworker takes off for whatever reason. We're allotted PTO. Why jump through hoops to convince ourselves that it's ok to use it?
I don’t even use a PTO day if I’m just feeling “blah” as long as I’m available via Slack to answer questions and can attend ad-hoc meetings. There are so many times I’ve had to/chosen to work late, I don’t say anything.
I don’t think I’ve taken a “sick day” once since going remote over 5 years ago. But for the last 10 years I’ve been leading initiatives first at startups and then at consulting companies and I mostly have autonomy and the trust to get things done.
It's because the GP doesn't value you as a person or trust you. In that worldview, you cannot allow any autonomy and all time not spent at work must be tightly regulated. It will also spill in other areas, and you can bet the GP is not well liked by their colleagues.
