How does Extra Foods punish their employees?

Hey, my friend just told me that they punish the employees at Extra Foods by physical beatings. I refuse to believe this, because this is Canada and the year 2010. There are laws against assault. His argument is that Extra Foods is owned by a large company, Loblaw, and doing anything against them would be futile. I don’t think so, assault is still assault. Do they actually dish out the beatings there, or is that incorrect?
