i dont get all this business talk but i work for a small business and they pay me over the minimum wage, but that reason is if they dont i'll just leave and go somewhere else. Working in a small business u dont get the same holidays, bank holidays and breaks like people do in larger businesses that have more people working for them.
I dont know if that has anything to do with it, but i suppose they need the workers more, bcoz i would prefer to work for a larger business if i got paid the same.
