Except work is nothing like professional sport. Your example is detached from reality.

It's more like being hired as a plumber and start doing secretary work for your boss for free.

There's a price tag on your services, why would give it out for free for some nebulous chance of getting a promo? Peak stupidity.

How's the boss going to know you can do secretarial stuff if he hired you as a plumber?

You go to the boss and you say you want to become a secretary. You and your boss outline a path with clear road and compensation for the effort.
