IUI process while working full time?

Hi everyone! My husband and I are starting the <a href="https://glowing.com/glow-fertility-program">iui</a> process. I work full time and was wondering how your employers handled your taking all the time off required for appointments? Did you fill them in on what you were doing or just take the days off ? Were you able to schedule days off ahead of time for testing before insemination or were they last min appointments? Thank you!
