Our Mission

We, the working men and women believe we have a moral responsibility to the future generations to leave the world a better place for all who come after us. Therefore, we, SEIU Local 99 in both public and private sector jurisdictions, are united by the belief in the dignity and worth of workers and the services they provide. We unite to form a stronger union to build power for ourselves and to protect and develop the welfare and interest of our membership and organize all working people through education and collective actions so that we shall obtain the best possible compensation for our labor, greater control over all aspects of our work and improvements of the conditions under which we work.We empower courageous leadership. We strive to enhance the strength and influence of the union while improving the lives of workers and their families. Our power and effectiveness depend upon the active participation and commitment of our members and solidarity with each other and our political and community allies.

Our strength comes from our unity and diversity. We must not be divided by forces of discrimination based on race, gender, ethnicity, immigration status, religion, age, physical ability, gender expression, marital status, and sexual orientation — we are standard bearers in the struggle for social, economic, global justice and civil liberties.

We pledge ourselves to provide the highest quality of services for our communities and ourselves.
