One labor law in place is mandated lunches and breaks. For example at the grocery store I work at, OSHA regulations state that if an employee works a 8 hour or longer shift they must have 2 15 minute breaks and 1 30 minute lunch. I believe this has had a overall positive impact on business. Making sure the employee is not overworked and also nourished through food is very important, if the employee has no breaks then they would be over worked and be less productive. When you get a break and also fuel your body with food you will feel better and work more efficiently and productively
