This is a prime example of why patriarchy is hurting men too, because what this guy is saying boils down to:

• We can make them work at any hour of the day because who cares if these guys have any life outside work?
• We don't have to do any work management, we just call those guys
• We can send them wherever, whenever
• We can create a toxic work environment and it's okay to treat guys like shit
• And those guys don't even complain because they need this job so bad
  Isn't it great?

The statement about "workplace laws" is so telling: Yeah, who cares about treating men with respect and dignity!?
It's not just about discriminating against women, it's also about mistreating men. That's what patriarchy is at its core: Pit men and women against each other and then reap the benefits. It's a "divide and conquer strategy".
