If you had a union, you could have a say in how promotions are handled. This is how the whole industry works. They will be more than happy to keep you low, doing useful work relatively cheaply, indefinitely. On the other hand, cry me a river. There are a million and a half families, including 3 million children, in the US living on less than $2/person/day.
