From the mid-1940s until his death, Linderman also held various jobs in the rodeo industry. In 1946, after sustaining the injuries that ended his season, he served as a judge for other performers. The RCA gave Linderman a position on its board of directors in 1947, as he was recovering from his appendectomy; At the time, there were multiple rodeo organizations awarding world championships; in addition to the RCA, there was the International Rodeo Association (IRA), which itself was created by a merger of two organizations. Linderman was sent to a November 1948 IRA convention, where he backed the idea of a single champion per event. The IRA stopped calling their season point leaders "champions" in 1955. While on the board, he pushed for the creation of an event to be held at the conclusion of the rodeo season, which would involve the leaders in the standings. His intent was to have the event play a large role in deciding the season's champions, which were determined by season earnings. In 1951, the RCA made Linderman its president, and he served six terms through 1956. During his time as president, the RCA agreed to a deal with the
Girls Rodeo Association (GRA), which mandated that rodeos comprising the RCA's schedule gain sanctioning by the GRA. Linderman's desire for a season-ending event came to fruition in 1959 with the founding of the
National Finals Rodeo. He was selected by those in the rodeo community to be arena director at the rodeo. Linderman returned to the RCA in 1962 as secretary-treasurer, holding the position for the remainder of his life. ==Personal life==
