You seem to imply that some people are fighting for discrimination between workers and non-workers. This is a weird point of view because most people fighting for worker rights are also sharing the fight for non-workers rights. But it happens to be very hard politically as the current political trend is to destroy social infrastructure and dismantle any kind of safety net and capital redistribution.
No people are asking for more rights for workers. Workers aren't any more disadvantaged than a farmer, homemaker or the unemployed. If you think people deserve paternity leave ask that from the government not the companies. So that everyone gets it not just the people with jobs.
