Does anybody read anything that I actually write?
yes, we do. you are talking about how it works now, and we are talking about how it needs to change.
if no one will provide the kind of cheap labour that can only provide living for you if you do it 6 days per week, then your customers will not run away from you, because the others will do the same. also, your customers also work somewhere, and they will be in the same position.
the solution is not to work seven days a week, the solution is to take back the wealth they are stealing from us.
