but the younger crowd not only sees them as office furniture but doesn't think twice about setting up a webex on the spot and summoning the mages, without a day of advanced warning and a calendar invite.
Ugh.. yes. Not just the younger crowd, but seems more likely from them. One of my largest pet peeves is people that simply think that if you don't have time on the calendar blocked out, that it means you're not busy. Even with a calendar invite, it drives me crazy when people will send one shortly before a meeting they want to hold, then get all pissy when you don't go. Sometimes I'm just too busy, sometimes it's because I don't sit there all day watching for stuff to pop up in email or on the calendar.
I have a basic rule of common courtesy where meetings are involved: invites should be sent at least a full business day before a meeting. I know that myself, and several coworkers plan our day around the meetings we have (and that we're actually going to attend). Not to mention, page/txt/whatever invitees if the meeting plans change close to the meeting time, and I'd defined "close" to be anytime within an hour. Just this week I had another case where I travelled to another building, went to re-check the room as I walked in the lobby, and found that in the last 15 minutes, they'd lost the room and converted to online only. Man that pisses me off. If I'd gotten a page/txt I could've saved most of the trip and avoided wasting nearly as much of my time.
Now for a "Holy crap! We've got a fire to put out!" Yeah, setting up a shared session/chat-room/conf-call whatever on short to no notice.. that makes sense. For your little "boy I'm having a hard time working through this..." no.
