kick upstairs

To promote one to a position that is higher but undesirable or that has little actual responsibility or authority. They kicked John upstairs to an assistant manager position so he would stop griping about his pay.

Promote someone to a higher but less desirable position, especially one with less authority. For example, Paul never forgave the company for kicking him upstairs at age 55. This expression alludes to its antonym, kick downstairs, simply meaning "eject." [Mid-1900s]

To promote to a higher yet less desirable position.

To promote someone to a higher rank with less responsibility in order to get him or her out of the way. Although one may tend to associate this expression with modern business practices, it was already being used in the early nineteenth century. J. W. Croker recorded it in an 1821 diary entry: “Lord Melville informs me that he is about to be kicked upstairs (his expression) to be Secretary of State.”
