Each year about this time MTI begins the process of developing its budgets for the ensuing fiscal year, in this case July 1, 2013 through June 30, 2014. MTI has two (2) budgets, one for MTI (the Union) and one for the MTI Building Corporation, the owner of MTI’s headquarters building.
MTI’s budget is the operating budget under which the Union provides services to the members of its five (5) bargaining units; i.e. the Teacher/professional unit (MTI); the Educational Assistants bargaining unit (EA-MTI); the Clerical/Technical bargaining unit (SEE-MTI); the Substitute Teacher bargaining unit (USO-MTI); and the Security Assistants bargaining unit (SSA-MTI).
This year’s proposed budgets are based on last year’s dues levels; i.e. no dues increase. This is the second straight year the Union has not proposed a dues increase.
