The foregoing analysis does lead us to ask, however, how frequently in industry disturbances arising over the failure to deal explicitly with intuitively sensed discrepancies between work level, payment, and individual capacity are fobbed off

as due to the unreasonableness and stupidity of individuals or groups, or to their unfairness, unscrupulousness, or down­ right dishonesty. The whole force of our considerations leads us to conclude that this kind of distortion is always liable to arise if the level of work in the jobs being argued about is not kept in the forefront of discussion. The evidence from indi­ vidual discussions at Glacier as well as from the great nation­ al crises that arise from time to time over wages and differen­ tials points strongly to the fact that level of work is rarely, if ever, considered-or at least considered effectively-on an agreed basis.
