Good morning... in the case of a multiemployer health plan maintained by one of the building and construction trades, an issue has arisen as to whether employees of some of the employers who do not perform work traditionally in the trade, e.g. clerical, could be permitted to join the plan. The concept would be not to include them as non-bargaining unit employees, but to actually have them join the union and participate as bargaining unit employees. Any knowledge as to whether this is permissible or not?
