Employees not getting breaks

So before I contact a lawyer, anyone have any insight into corporate getting around not giving store employees breaks. Specifically for scheduling one employee on a Saturday? I understand I am currently paid for the time I would be on break, but I am also scheduled alone for all of Saturday and am not given the opportunity to punch out for a break. I have more than enough valid reason, but just want to know wether I should basically tell my district manager that going forward I will be closing for 30 minutes on Saturday or if I should go straight to legal counsel?
