Could you work only knowing what your schedule was less than a week in advance? or (like 15% of low-wage workers) less than 24 hours in advance?
The Living Wage Foundation, found this experience for over half of low paid workers; the risk of fluctuating demand has been pushed down to them to deal with.
How can you arrange child-care, school meetings, health appointments in such an environment?
Low wage Britain is hard work for the poor & the middle classes often just don't see it!
