There's no reason a cashier should be forced to stand 40 hours a week. The right to sit is enshrined into law in other countries such as the U.K., Germany, and Finland. Workplace Regulations 1992 stipulates "if staff can sit while they are working, the employer must provide suitable seating". Cashiers at all major supermarkets get chairs in the U.K. Why don't we?
Things could be better in Canada. I'd be very surprised if this site fixes Canada's high food prices, but it might light the spark that gets a 58 year old mother of 3 a stool. We as Canadians can solve any problem if we put our minds to it. I believe that if we work together we can let cashiers sit, and maybe even one day make sure our neighbours always have enough to eat.
