"In the manufacturing world, it was once a very common practice for promotion to happen on a seniority basis and I've personally seen the devastating effects of putting the wrong person in the wrong job. In all honesty, I was promoted into my current Production Supervisor role based on my tenure with my company. But, for many years, the manager of my department consistently put in my performance reviews that I would be the top candidate for a supervisor position if tenure wasn't involved. In my mind, technical skills and people skills are the best traits for advancement to new jobs rather than simple time put in with the organization."
