director of program eats lunch daily with teachers isn’t that unprofessional?

I work at an elementary school which has preschool. The preschool has a director rather than a principal. This director eats lunch daily with her favorite group of teachers and gossips with them. Is this not highly unprofessional??? Apparently this is a daily

thing I don’t go to staff room during prep so I didn’t know until today but other teacher that’s not part of the group told me. Now I definitely don’t want to go to stage room if my boss is in there everyday
