The Union sought to amend Certification No. 3-88 to add the titles Program Manager, Training and Development, Levels I and II; Assistant Director of Workforce Training and Development Managerial Pay Plan II and III; and Director of Workforce Training and Staff Development. HHC argued that the titles were excluded from collective bargaining. The Board found that the employees in the titles are eligible for collective bargaining and appropriately added to Certification No. 3-88.
