There's some news that doesn't need to be shared with your boss. Anne Fisher suggests avoiding the following topics.

Your love life. Even if you're friendly with your boss, sharing possibly unflattering details of your romantic life can negatively affect the way she views you in the workplace.

Criticism of coworkers or higher-ups in your organization. Griping about colleagues can sound like tattling; gossiping about executives is dangerous politically, not to mention indiscreet.

Financial problems. This reflects poorly upon your ability to manage your life. Never cite money problems when asking for a raise.
