Times were tough during the Depression years, and in 1930 he was out of work for several months in Melbourne. He returned to Willatook for a short time and then moved to nearby Koroit, near Geelong, where he worked in a local garage. At first, this was unpaid, but after a while, he made himself indispensable and began to be paid for some of his work. Two large jobs helped him turn his work at the garage into a full-time job. George recalled that the garage was a wonderful place to gain skills and experience.
His education had only just begun, and he enrolled in evening classes in mechanics and management at the Gordon Institute of Technology in Geelong, where he finally realised his dream of becoming an A-grade mechanic. After qualifying, George was asked to teach aspiring motor mechanics in evening classes at the Gordon.
During the Second World War, he became a production engineer and then manager of a munitions factory and, being classified as an essential worker, was not allowed to enlist in the armed forces.
From 1943 to 1945, George studied Industrial Management and Executive Training at RMIT and was awarded the John Storey Award from the Department of Industrial Management. He was asked to teach at RMIT as soon as he had finished his course, which he did for three or four years.
