The top lessons you need to learn with a Leo is your boss...With a Leo in charge, be prepared to work tirelessly, because he or she will be burning the midnight oil. Leos think big. They have energy and pizzazz.
You may grumble if you think your supervisor is showing off, taking all the credit, and hogging the spotlight, and perhaps that's true, but you won't find a more honest workmate.
Maybe you'll have to put up with some bombast, but it will be hard to dislike the Lion! Just remember to show respect (which you should do anyway!), offer compliments, and be steadfastly loyal. You'll feel like a member of the pride in no time.
