one brother is the main boss and he lets his brother get away with everything.. and punishes everybody for his brothers mistakes...promoted him and everything...
If none of the workforce has an employment contract or a union membership, then everyone's an "at will" employee and therefore can be fired without notice at any time for any reason or no reason at all, and everyone can quit without notice and for any reason or no reason. Likewise, the employer can do less than fire someone, like demote them, reduce their hours or salary, or punish thejm for their brother's error. There's no law against nepotism, unfortunately, it's just part of "office politics."

Your choices are to quit, learn to live with the fact that the brother is going to get preferred treatment or go over the main bosses head and complain to the owner, if he is not the main boss.
