How do you manage having "multiple bosses"?

Treat them how they treat you

You need to gauge their personalities and meet their needs as best as possible.

I answered politely to my bosses to their questions

You get good at juggling them. In a corporation, you have your boss and, when corporate shows up, your boss' boss. If you have a manager and assistant manager, it's a bit easier.

Don't ;) Find a way to single thread things. Make a priority list and make them sort out the order. That is their job, not yours.

Not easily here. One will get mad if you're working for the other, etc. It's ridiculous.

that hard because they are not always on the same page

Open dialogue, clear priorities, regular 1-1’s

You have to understand what is important to each of them, and what is important to getting your job done. Then you have to strike a balance.

If they are good leaders, it's easy to discuss priorities and goals. If they are incompetent, a single one is already a nightmare.
