Using the word "welcome" frequently can significantly enhance communication within a team. Leaders who actively maintain an open-door policy foster an environment of trust and collaboration, which encourages healthier interactions. This openness not only helps in building respect but also facilitates team cooperation and buy-in from members.

According to Susan C. Young in "The Art of Body Language," such an approach is vital for effective leadership. By promoting transparency and a relaxed atmosphere, leaders can optimize non-verbal communication, leading to a more positive and impactful workplace environment.
