text_A: In July 1962, Oswald was hired by the Leslie Welding Company in Dallas; he was disliked and quit after three months. On October 12, he started working for the graphic-arts firm of Jaggars-Chiles-Stovall as a photoprint trainee. A fellow employee at Jaggars-Chiles-Stovall testified that Oswald's rudeness at his new job was such that fights threatened to break out, and that he once saw Oswald reading a Russian-language publication. Oswald was fired in the first week of April 1963.
text_B: If Oswald had felt differently about the work he was doing at the Leslie Welding Company would he have probably stayed there longer than three months?
DON'T KNOW.
