ABSTRACT
This chapter demonstrates the existence, among Chicago schoolteachers, of what has been called a "horizontal" plane of career strivings and movements. It traces the kind of career patterns which occur, at this level, in a public bureaucracy where movement is achieved through manipulation of formal procedures. The career patterns which are to be found in the social matrix are not expected to be typical of all career movements of this horizontal type. It is likely that their presence will be limited to occupational organizations which, like the Chicago school system, are impersonal and bureaucratic and in which mobility is accomplished primarily through the manipulation of formal procedures. Any move from the school would mean a loss of such position and its advantages and the need to win colleague acceptance elsewhere. Ecological invasion of a neighborhood produces changes in the social-class group from which pupils and parents of a given school are recruited.
