 Although her research was progressing at Missouri , McClintock was not satisfied with her position at the University . She recalled being excluded from faculty meetings , and was not made aware of positions available at other institutions . In 1940 , she wrote to Charles Burnham , " I have decided that I must look for another job . As far as I can make out , there is nothing more for me here . I am an assistant professor at $ 3 @,@ 000 and I feel sure that that is the limit for me . " Initially , McClintock 's position was created especially for her by Stadler , and might have depended on his presence at the university . McClintock believed she would not gain tenure at Missouri , even though according to some accounts , she knew she would be offered a promotion from Missouri in the spring of 1942 . Recent evidence reveals that McClintock more likely decided to leave Missouri because she had lost trust in her employer and in the University administration , after discovering that her job would be in jeopardy if Stadler were to leave for Caltech , as he had considered doing . The university 's retaliation against Stadler amplified her sentiments .
