I have had this boss, unfortunately. To a t. He'd tell me a project was "completely up to me," that I was "the leader" of it, and that I should feel "totally empowered" to make decisions, allocate resources, etc. He proceeded to show up to each of my project meetings, often late and out of context, disagree out loud, offer unsolicited opinions, micromanage, and badger me into implementing his ideas -- thoroughly undermining any ostensible authority I had over the project, or reversing any progress the team had made up to that point. His ideas came in two flavors: a) completely off-the-cuff and unconsidered, and b) foregone conclusions (what the team and I liked to call his "pet" ideas). Both of these types I had to entertain, and often to implement. And of course, when it came time for him to chip in with the execution in any way, or even to explain his rationale, he'd bolt for the door.
Essentially, I was his task rabbit. If a project went to shit, he'd claim it was "mine" and be able to pass the buck accordingly. If it went well, he'd swoop in and scoop up the credit. Attempts to talk to him about it in one-on-ones went nowhere. Attempts to "check in" with him prior to meetings, in the hopes of pre-selling him on a plan, went nowhere. He'd be dead set on a pet idea, and it was my job to "totally lead" the execution of that idea.
Bosses like this are toxic. I'm not sure I've ever found a good way to work successfully with this personality type. If this describes your boss, figure out how to transfer, how to escape, or how to develop Vulcan-like mastery over your anger and your pride. Some tigers can't change their stripes, and I can guarantee you that this kind won't.
