Is it unprofessional for me to tell my manager that I have to leave exactly at 4:45 every Wednesday for a private commitment without saying what it is?
I have a fixed personal commitment every Wednesday at 5:15 p.m., and I can't miss it or change its time. It's not a doctor's appointment, or counseling, or anything related to children - it's just something that's important to me personally and that I don't want to share the details of at work. My job is usually very flexible with schedules as long as everything gets done, but my manager has recently started scheduling team check-ins on Wednesday afternoons, and they tend to keep going until after the end of the workday. When I told her that I have to be out the door at 4:45 on Wednesdays, she asked me why and seemed a little surprised when I told her it was a private commitment I'd prefer to keep to myself.
I said I could open my laptop early on Wednesdays or skip my usual break to make up the time, and she said that was fine, but I feel like she's still curious about what I'm doing. Am I supposed to explain the real reason? Is it weird or unprofessional to have a clear boundary that I need to leave at a specific time every week without giving the full background? I'm trying to maintain normal boundaries between work and life, but at the same time I don't want to seem like I'm hiding something or being difficult to deal with. How do people usually handle recurring personal commitments without giving their manager the full explanation?
