The Belgium national football team is currently competing in the 2026 World Cup. Fans are numerous in wearing their favorite team's jerseys, but can they be worn to work? According to Linda Cappelle, CEO of Bright Plus, specialized in human resources, it depends on the company's context and the person's role. Dress codes vary from one company to another and it is important to choose an environment that matches one's values and norms. The Belgian national team's jersey, the Red Devils, is very trendy this year, especially the outer jersey with turquoise and pink colors. But wearing a football jersey to work can give a bad impression if it does not match the prevailing dress code. It is therefore important to ask your superiors in case of doubt. Informal initiatives can strengthen team cohesion, but it is important to integrate them into the company's context and rules. The World Cup is an important event for fans, but it does not change the basic rules of a company. Professional appearance must always prevail, especially depending on the meetings, trips or online calls planned for the day. Organizations must define clear expectations and open and clear communication is the key to avoiding misunderstandings. The Belgium national football team will play on June 15, 21 and 27, and fans are eager to support their team. With the right attire and a professional attitude, they can show their team spirit while respecting their workplace's rules.
