I work in the US in a office/research environment, and typically eat lunch at 11:30. My schedule is usually pretty open, but I've noticed that lately people are scheduling many, if not most, of their meetings with me during that time. On occasion I meet with people who have completely full schedules and lunch is the only time they can squeeze in, and in those cases it makes sense and I'm happy to oblige.
However, I think a lot of the time that time choice is just a casual/arbitrary decision on the part of the meeting maker. Lunchtimes in the office vary (12:00 and 12:30 are also common), so it may not seem like "lunch time" to others. I have my own reasons for wanting to eat on a consistent schedule when possible, and have been thinking about creating a recurring daily outlook appointment with the name "lunch" as a soft deterrent for people who might think that 11:30 is as good a time as any.
However, I'm a little worried about how it will come off. I've seen it done in other workplaces but it's not common at my current job. I don't want to seem uppity or passive-aggressive, and I also don't want to make up anything or lie about why I want to block off that time for most meetings.
Is it generally acceptable to make "lunch" calendar appointments? If so is there a better name for that type of appointment?
