According to common sense and common definition, eating overtime meals is usually not considered as a group building activity. The main purpose of league building is to promote communication and cooperation among team members, improve team cohesion, and thus improve work efficiency and teamwork ability. Eating overtime is usually because of work needs, and it may not be able to achieve the purpose of group building.

But in some specific cases, if the company combines overtime meals with group building activities, it can also be regarded as a group building method. For example, the company provides rich meals when employees work overtime, and organizes team activities and games during meals to promote interaction and communication among employees. Such activities can be counted as part of the league building.

In short, eating overtime meals is usually not a group building, but under certain circumstances, if combined with team activities and interaction, it can be regarded as a group building method.
