What was she receiving before her SS kicked in? You don't work under the table your entire adult life unless you are trying to hide something from the welfare office.
How did you control yourself during this conversation? I wouldn't have been able to contain myself.
She went from living on welfare (via breeding) to “retiring” on welfare. The co-worker was trying to do the same until welfare reform forced it into the workplace. She earns little because she merits little; she knows if she tried to bargain for better pay her resignation would gladly be accepted. No English skills, no work ethic, files using folders for “Mr.” and “Mrs.” instead of last names, etc.
