Full members of the union automatically receive full employment protection, up to and including free legal representation in most job-threatening situations, a $1,000,000 liability insurance policy from MTA should you be sued by anyone in connection with your work, and access to three free half-hour legal consultations on non-tax-related matters with a discount of up to 30% for further legal services through MTA's legal referral service. Members have the right to vote in all MSP internal elections, the right to participate in MSP General Assemblies, and a voice on important decisions. Only members may serve as departmental representatives, board members, officers, or expense-paid delegates to the anuual MTA and NEA conventions.

Finally, members receive substantial savings through discount group purchasing of auto insurance, life insurance, homeowner's and renter's insurance, mortgage re-financing, vision care, tax preparation, home heating oil, and travel and entertainment services. The home-heating oil and auto insurance discounts alone can provide over $600 in savings in a single year.
