Ah...I found the problem. It's due to my poor reading skills apparently :-). I thought that the employee had scheduled a meeting, time included, themselves, and not paid enough attention to realize what they'd already committed to. You clearly said the manager scheduled the time, not the employee - all the employee had asked for was a meeting sometime. If I had only read more carefully, I would have not been nearly this confused! Sigh....
???
Now I'm confused.
The staff member requested the meeting time and then later asked to change the meeting time. The manager agreed, but called the request "bold."
Ok, then I'm back to thinking it's rude, lol.
Your initial quote was:
"A Gen Z staff member requests a meeting with their elder millenial supervisor. The supervisor agrees and later on sends a meeting invite.
The Gen Z staff member writes back saying that they've re-assessed their schedule and noted that they have a lot of intense back-to-back meetings that day, and would likely not be in optimal shape for the meeting with the supervisor and asks to reschedule it to avoid burnout."
The second time I read it, I thought that the underlined meant the Gen Z staff member said, "Hey boss, I need to meet with you because I need to talk about x, y, z." Boss then says, "Sure I'll schedule a meeting and does so on Friday at 3:00." Gen Z staff member says, "Oh, yeah, I've got two meetings on Friday. I don't think that'll work. I'll be burnt out."
If it's that situation - no problem.
Originally, I thought it was Gen Z staff member said, "Hey boss, I need to meet with you on Friday at 3:00 PM because I need to talk about x, y, z." Boss then says, "Sure I'll schedule a meeting and does so on Friday at 3:00." Gen Z staff member says, "Oh, yeah, I've got two meetings on Friday. I don't think that'll work. I'll be burnt out."
If it's that situation - which is what it now seems like it was - then Gen Z staffer is being at least a little rude. The rudeness comes from not thoroughly checking whether or not you could keep a time commitment before you book someone else's time. Ultimately the manager might not have minded, and that's fine. I probably wouldn't have minded much if it didn't inconvenience me - make scheduling some other meeting harder because I had this one scheduled...or in some way keeping me from making some plan because I thought I had this meeting scheduled. Also, the longer the meeting has stayed on there, the ruder, in my mind, it becomes. If I asked for a Friday, 3:00 meeting on Monday at 3:00 PM and rescheduled it first thing Tuesday morning - not too big of a problem. If I asked on Monday and rescheduled it Thursday at 4:30 PM - more rude. Perhaps it was much closer to the Monday/Tuesday situation and nothing was negatively impacted since the manager thought it wasn't a big deal at all. I dunno.
I think it's pretty straightforward that it's rude to book someone's time up for a Friday at 3:00 meeting when you had a doctor's appointment on Friday at 3:00 already scheduled. You couldn't do it. You should have known you couldn't do it. The situation didn't change - you just didn't take the time to look before you scheduled a meeting. That's not valuing someone else's time. This is the same in both situations.
It always frustrates me when I feel like someone throws out a buzzword as "a trump card," which, I think, is why this one frustrated me. It's rude not to value someone else's time in this way in general, but if you throw out the phrase "burnout" then it becomes something different - not in my mind.
After thinking on it myself, this is why I was frustrated by the situation, I believe.
You only think it's rude because you're thinking about it from a certain perspective.
Now think of it with a different frame.
I request a meeting with you for 3pm, you agree and send a meeting invite. I realize I've made a mistake requesting the meeting at that time and I know I'm not going to be in great shape for the meeting because of the other things I have on my plate.
I can
a) suck it up and go to the meeting anyway because I requested it, and corporate culture rules dictate that it's rude to request a change
b) just be honest with my manager like they're a human being who might be totally okay with moving the meeting, because it might not actually be a big deal, and if it is a big deal to move the meeting, she can just say "no" because she's the one in charge.
Plus I'm just explaining the objective fact that I won't be in great shape for the initial meeting time I requested. As my manager, it's sort of her job to care if I'm overloaded, so if she can easily accommodate it, then there really shouldn't be anything wrong with just being honest and *asking*.
For me as a manager, I would want my staff to feel free to request time with me, and I would want them to feel free to ask for meeting changes even if the reason is just "Ugh, I realized I have XYZ procedures right before and I'm going to be cranky."
It's not rude to me because I'm the one with all of the power to grant or deny their requests. They're just giving me more information to work with to make wise managerial decisions.
As the person in charge of them, I am the custodian of their well being every single day. So yeah, if someone schedules a meeting with me at the end of Thursday and then later on realizes they have 3 patients from hell scheduled right before and volunteers that they made a mistake with their meeting time request, then OF COURSE I want to know that.
At the very least, if I can't move the meeting, I want to be aware that the staff member coming into that meeting is going to be totally fried and not want to be there. That's useful information to me.
If you aren't conditioned to see the scenario through the existing corporate culture lens, then it truly doesn't make sense to call the behaviour bold.
I've quite literally had staff do *exactly* this same thing to me, often for performance reviews. Performance reviews are stressful and I've had staff request to reschedule them just 10 minutes before.
I don't want a miserable, exhausted, burnt out staff member in a performance review! Of course I'll reschedule if there's any way to do so, or I'll let them switch with someone. Caring about their state of being makes a HUGE difference to their experience as my staff member.
I won't always grant requests, but I will always want to hear them, and if I deny them, I will give a reasonable explanation why. From my perspective, if a staff member asks me for something, the onus is on me to justify why I won't give it to them. The onus is on me to make them feel like what they want and need from me matters to me.
So no, I don't find anything about the situation rude at all. You can't impose on someone who has all of the power in the dyad, you can only request and explain your requests and hope that their priorities will align with yours.
