Mr. McDonald acted as the Chief Operating Officer, project manager and President at the OSI group. Dave has also worked at the North America meat Institute as the chairman. After Marfrig Frigoríficos acquired the operations of the OSI Group in Brazil and Europe in December 2008, Dave also served there as an independent director. Mr. Mc Donald has also worked at the United Steelworkers of America from the year 1952 to 1965 as the American labor leader.
In the year 1923, Dave was introduced to Phillip Murray by a friend where Phillip hired him as his secretary. This is because he was delighted with his high typing speed and also the fact that Mc Donald had pioneered the formation of the Alumni association of the Holy Cross High school. He was also the alumni group of the Catholic Pittsburgh, and they later became very close friends.
Later on, Mr. Mac Donald enrolled for classes at the technology institute of Carnegie, currently known as the University of Carnegie Mellon where he took his dancing and drama classes. He graduated in the year 1932 as an amateur actor. He was called for an interview by a Hollywood movie firm called Warner brothers to discuss on a post for him as an assistant movie director but turned down their offer.
While Mr. McDonald chaired the board of OSI, he highly believed that offering more and better services to his customers had no limitations to the company’s production. Instead, it gave the company more customers and in the end, increasing their sale. He also helped increase the company’s sales, publicity, as well as market its products through early engagement of its customers. David also engaged in discussions regarding the remedies and solutions they might want to improve in the production of their goods.
In May 1962, Mr. Dave received a degree in Industrial relations from the College of St Martins. In the same year, union members from the steelworkers felt that Donald was not protecting their interests hence Dave started negotiations on their job security provision which greatly helped save the workers’ jobs. After the company had recovered between the year 1963 and 1964, it recorded a profit that led to an increment of the worker’s salaries.
