Generally, among men at work promotion comes by performance, however, it is not restricted to it. Promotion can generally come by employer but there is another promotion agent. That agent is the individual himself: workers with strategic thinking minds called it Job Hopping. Apart from salary increment I mentioned two weeks ago, by Job Hopping I promoted myself from entry level of Personnel Officer in my first company of employment to Director of Human Resources after several hops. I agree it is not possible for every worker, but with correct knowledge, Relevant experience and strategic reasoning, it is possible. I equally agree that these three conditions are very scarce in this 21st century.
