Largely because of these rules, our urban schools better resemble bloated, civil-service bureaucracies than efficient, professional academies of learning.
The problem of union-precipitated bureaucracy is especially acute in urban schools given that union fundraising and organization greatly outstrip the political resources available to urban parents. Given this disparity in political influence, urban-district teachers unions negotiate, disproportionately, with themselves: unions on one side of the table; union-backed school board members, often elected specifically because of union support, on the other.

This is obviously a heated issue all around.
