What is the best way to maintain a formal or informal style of address in a work environment?

The choice between formal and informal styles of address in a work environment depends on corporate culture, communication context, and participants' preferences.

Recommendations:

• In new or official communications, it is better to use a formal style (e.g., "You", surnames) to show respect.
• In teams with a friendly atmosphere and long-term cooperation, an informal style (using "you" names) is acceptable if it is customary.
• When in doubt, it is better to start formally and switch to an informal style upon agreement.
• In written communication (email, documentation), a formal style is preferable.

The main thing is to respect the interlocutor and maintain a comfortable atmosphere for communication.
