At the risk of my management reading this, here is a little trick which leads to faster promotions.

Plant the “promotion seed” in your manager’s mind far before you think you’re up for a promotion.  This is done by simply asking your manager if you will get a promotion at the next opening.  While it may seem innocuous, by having them think about you getting a promotion, you have planted the seed for consideration of a promotion.

Managers have an internal clock of how long they need to consider someone for a promotion before they act on it.  By making them “consider” you earlier, you have started that internal clock sooner.  This has the double effect of additional pressure on a manager knowing that you expect a promotion from them.  If there is no pressure, then the manager thinks you’re okay with your current level and has no guilt about not promoting you.

Do this whenever you get a new manager, or right after you just got a promotion.  For example, I waited 2 months from getting a promotion before I planted the next seed.
