This video was leaked by a concerned insider. It depicts what seem to be hired actors posing as employees. They explain why unions are not needed and that they are only after the workers money. Walmart, the biggest company in the world in terms of revenue, is notorious as a major promoter of low wages and casualised work. This is not mentioned. Although this is in the United States, stagnant wages and casualised work are a reality in Australia too.
