What was one purpose of the 1836 strike in Lowell, Massachusetts? to demand freedom of speech
to gain the right to organize
to protest reduced pay for mill workers
to demand equal rights for women

please give me the right answer

An informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
