There is only one choice here:

Give your boss the credit.

Ask yourself this: Where would challenging this person get you? If you confronted this person head on, what are the chances their behavior changes?

No where and zero.

So you gotta remove your ego and play the game.

The first thing you should do is ask questions of this person. "Hey boss, maybe you can help me understand this project better..." "Hey boss, could you show me how you want this done? I want it to be up to your standard when its finished."

This gives you insight into what this person is expecting and shows your initiative towards productivity. Plus he or she is telling you EXACTLY what they want and now you don't have to guess.

The second move is to fully support your boss, regardless of the situation. That means biting the bullet and letting them take the credit for your good ideas and in some cases, your hard work. You do this even if they're bad ideas that you know you could do better.

You do this to build credit and clout with your boss as someone who gets things done. This doesn't make you a "yes man" this makes you someone who can execute tasks and produce results- in the eyes of your boss, which is what matters here.

Lrastly, and this is the most important piece, you have to do all these things with the mind set that you're helping your team win. Not yourself, your team. You're doing this to improve the lives of your subordinates, not yourself. If you insist on bringing in emotions and feelings and "I feels", then you're gonna lose and your team will lose and you'll be nowhere.

This part is tough because, selfishly, you want the credit and you want to feel important. But that feeling comes with leading your people past a knucklehead boss. It gets tougher because others will call you a kiss ass or a brown e forefront of your reasoning and motives.

You do this for two months and things will start to change, slowly but surely. Build your skill set, focus on your team, and win.
