I think maybe you're misunderstanding my frustration. This TM doesn't like the changes modernization has brought to their job. I get that - a lot of us don't. My problem is that instead of trying to do these new things (to them) in a way so as to finish up on time, they sort of meander around, taking lots - lots! - of extra steps and really, as I think about it, kind of trying to make things take longer. Since I've done way more push than this TM has, I've tried offering suggestions; they were not well received so I backed off. Some people like to figure things out on their own and that's fine. Except they haven't figured it out and don't appear interested in figuring it out. That's what I'm frustrated about.
I don't expect this TM to ever stay extra if that's inconvenient. I do expect them to actually try to do a good job, and I don't think they are. They're not doing what they hired in for and they're mad about it and tough rocks for everyone else. Unfortunately for me, because of the area where we both work, I'm in the direct line of the fall-out.
