A younger colleague was recently awarded tenure and is of course very happy about this. In his case, tenure was not such a sure thing, adding additional anxiety to a process that is stressful anyway, and, now that tenure is assured, accentuating his feelings of relief.
This colleague is still basking in the relative security and prestige of associate professorship. One aspect of his basking is to decline to help with some activities that he formerly did as an assistant professor. Recently, if one asks him to help with something, he typically says "I don't have to do that. I have tenure." or "Ask X to do it. He's an assistant professor."
I am happy for him, but I find these comments obnoxious and I hope he gets over this particular phase soon. I don't think he was particularly burdened with university and professional service tasks as an assistant professor, so I attribute his recent behavior to post-tenure exuberance.
That's fine, but his refusal to help with some tasks means more work for others, tenured and non-tenured faculty alike. And if he keeps doing such things, at some point he will no longer be a happy tenure puppy but a slacker tenure dog, and that's not nearly as cute.
