How appropriate is it to use the informal address "you" in a professional environment?

The use of the informal address "you" in a professional environment depends on the corporate culture, context, and relationships between colleagues. In some companies and teams, it is normal and fosters a more friendly atmosphere, while in others — it may be perceived as a lack of respect.

It is recommended to consider:

• official company policies;
• the communication style of management;
• the preferences of the interlocutor.

If in doubt, it is better to use the more formal "you" until a closer contact is established.
