So much time is spent in the office that blurred boundaries are almost to be expected. However, the line between professional and personal can become too indistinct, potentially leading to embarrassment, strained relationships, and even career risks. According to etiquette expert Laura Windsor, certain actions violate unspoken office rules.

Windsor, who spoke with the Daily Mail, emphasizes that every workplace relationship should be founded on mutual respect, professional boundaries, and genuine goodwill. She has identified 11 specific behaviors that can undermine these principles.

Among the highlighted missteps is the concept of a "work husband" or "work wife." While a close, platonic friendship can offer emotional support, Windsor warns these relationships can become complicated. She notes that what begins as light-hearted interaction can become emotionally draining, particularly if personal lives lack fulfillment. Signs of an unhealthy dynamic include prioritizing a work colleague over a partner or constant comparison. Windsor suggests that if such relationships become a noted problem by human resources, it's time to re-evaluate boundaries.

Using a phone during meetings is another behavior Windsor advises against. She explains that checking a device while someone is speaking sends a message that the screen's content is more important than the speaker, indicating a lack of self-control and a short attention span. Effective leaders, she notes, offer full attention, maintain eye contact, and listen actively.

Eating at one's desk is also discouraged, unless absolutely necessary due to deadlines. Windsor suggests that noisy eating habits can be disruptive to colleagues. She advises maintaining good posture, eating discreetly, and keeping pungent foods at home to avoid offending sensitive noses. The expert also strongly cautions against taking food from the communal fridge, deeming it poor time management and a form of stealing that can damage integrity.

Regarding attire, Windsor advises against open-toe shoes, particularly flip-flops and beach sandals, in professional settings. She also states that removing shoes at one's desk is inappropriate. Changing shoes at the desk is also discouraged; Windsor recommends using a restroom for such adjustments, along with applying makeup or grooming.

Lengthy personal phone calls are another office no-no. Windsor suggests keeping personal calls brief or saving them for breaks away from colleagues, as open-plan offices amplify sound. She adds that no one wants to overhear detailed personal conversations.

Windsor also advises against coming into the office when sick, stating that while it might seem admirable, it can lead to the spread of germs in shared spaces and won't be appreciated by colleagues who may be more susceptible to illness.

Discussing politics is identified as a sensitive topic that can lead to heated debates and long-lasting judgments, making it unsuitable for the workplace. Finally, Windsor warns against excessive drinking at work social events, noting that alcohol can lower inhibitions and lead to behavior that is memorable for the wrong reasons.
