Not anything specific, but when I ask someone at work about something, they say no, and in my mind, that's the end of it, but they feel the need to continue on, until i either have what I asked for, or the issue is resolved. When it doens't alwasy need to be. For example, do we have a membership in a particular org. as I need to *try* and get a copy of something they put out. If we do, great, can I have that info so I can get what I need, but if not, the world won't end.
I had one CW, who thankfully is gone, we dubbed "Useless" since he was. He unfortunately was the one I had to ask these types of things for, and in spite of me needing a simple yes or no, he'd then take it upon himself to find it himself, calling and emailing people he thought MIGHT be able to help, and so on, which was completley unnecesary, and a waste of time. It drove me nuts.
I have another CW who does the same thing; she's a bit paranoid and one who thinks no stone must go unturned, when my view is yes, sometimes, but other times, if something isn't available, or I'm not specifically ASKED to do a certain task, then I'm not going to, as its not "an efficient use" aka waste of my time.
She will then go on about it, and take it upon herself to do whatever it is SHE thinks needs to be done, when its not even her responsiblity. She's so afraid someone in her group, aka her boss, will come down on HER for not having this info, when many times, its not even necessary. Where I am more laid back, and know what needs to be done, and must be done, vs. what would be nice, but not a requirement.
