after years of being an executive chef I became a sous-chef for a chef who was about to take maternity leave!
best experience of my life. the kitchen is a ship, and all of it's sailors each appreciate each-others role and importance. If you see changing positions as downgrading, then you are blind to the true nature of kitchen.
besides,if its power you're after, then the guy cooking the food has the most control REALLY....executive chefs keep jackets clean ....LOL
have fun and keep your eyes and heart open in the kitchen, has always worked for me!
