To keep expenditures low in the early years, Mr. Bartter served as the only employee. At the annual meeting in 1960, board members voted to pay him $100 for his past year of service. This increased to $250 for that fiscal year, and in 1962, the board voted to pay him $50 per month for serving as the credit union treasurer. During this time, Mr. Bartter continued his full-time positions as an industrial arts and mechanical drawing teacher at several area high schools. He worked the hours necessary to maintain the credit union after school.

The first part-time employee, Gladys Heath, was hired in December 1962. Another part-time employee, Mary Ann Remick (nee DeLong), a high school student at the time, was hired in October 1965. Elmer Woods was then hired as assistant treasurer and assistant manager in January 1969. He remained an employee of the credit union until his retirement in May 1988. Edward Enyedy, a teacher at Midview High School, took over that position in 1991.

In 1980, Mr. Bartter quit his teaching position and began full-time as the manager/treasurer. In 1991, the board appointed him as president and chief executive officer, a position he held until his retirement in June 1997. In preparation for the future, the board formulated a succession plan to allow Edward Enyedy to learn and grow into the position. Following Mr. Enyedy's resignation, Deborah L. Humbert took the helm to help phase in the credit union’s new data processing system. In early 2008, Brent Binkley, SELCCU’s chief operating officer, was appointed as president and chief executive officer.

Throughout the 1980s and 1990s, more employees were hired as the numbers necessary to maintain this growing business continued to increase. In June 1990, the credit union created a subsidiary corporation called Member Plus CUSO (Credit Union Service Organization). The CUSO was established to offer financial services including financial planning for the credit union members. Today, the SELCCU has 33 full-time and five part-time or seasonal employees.
