history: Any time my boss asks for my ideas and they work, it becomes "Our idea" and then "his idea", but if it fails it's "your idea".
current: I'm just thinking about quitting my job. My boss is the worst; every time he asks for my idea, if it works it becomes "his" idea and if it fails it's "your" idea.
next: That would be annoying. If there is anybody over him, you might try reporting it first.
