I block off my prayer times on the shared calendar now, in plain sight, and I don't explain them anymore. When a meeting request lands on my holy day, I decline it without a paragraph of apology. It took me years to stop treating my faith like something I had to sneak around at work.
More people experience this than they realize.
You honor your faith and your work together and ask for what you need without apologizing.
If this sounds familiar, the Library can help you find the bigger picture.
