Walmart is worried. They are so worried that the Democrats are going to win power in November that they are mobilizing their local management teams to work towards defeating as many Democrats as possible. To hopefully accomplish this, they are holding mandatory meetings with employee's that are designed to inform them "wink wink" of the supposed dangers of having Democrats in power.
Why are they going to the trouble of telling their employees how to vote you ask?
Because if Democrats win, they might pass legislation making it easier to unionize which would in turn force the world's largest and notoriously anti-labor retailer to actually pay their employees a living wage, including, heaven forbid, health benefits.
