" The "financial support" clause of Section 2 does not appear to have been broken, since the employer is allowed to confer with the employees on company time. The only point of question is the direct management participation in the committee. This could be interpreted as being more than conference. The employee committees, in order to fulfill the criteria of Section 2, would have to be comprised strictly of employees. These employees would then be able to conference with management, but management would not be considered an active participant or a voter in these committees. However, in an architecture firm where all employees are professional and projects are often completed collaboratively, the union's dogmatic schism between "labor" and "management" is probably anachronistic. In that type of business, those definitions are more fluid, such that "management" on the committees may not be any different from...
