Mother's work 135 plus hours a week without scheduled breaks and without a quiet lunch time. They multi task, active on their feet, rarely a moment to rest. They are not allowed holidays off, but are expected to work even more on holiday. They need basic medical skills, kitchen skills, home keeping skills, and communication skills, and more. And at the end of the week, her only "pay" is the satisfaction of surviving another thankless week and a job well done.
