Be Part of our Circle. We empower people to live their best life. That is our mission—not only to those we serve, but to those we employ. This mutually shared sense of purpose drives our decisions and actions. Come as you are and achieve better lives as part of the St. Louis Arc family of individuals in this vital role. In this part-time role, relief staff can take advantage of a flexible schedule! After completing a 4 week training period (24-28 hours per week), relief staff work a flexible schedule of 25 hours or more per two-week pay period.
