While it varies from state to state, most states, including Wisconsin, New York and Illinois have laws that prohibit employers from making employees work 7 consecutive days. Some states, such as California, allow employees to work 7 days a week, but require employers to pay double time for at least one of those days.
Labor allowance laws can vary pretty drastically between states. For the most part, in the United States, it is either illegal to make a full-time employee work 7 days out of the week, or there are required bonuses for workers who are forced to work every day in a week. There are laws in Illinois and Wisconsin that are called 6 days out of 7 laws, which prohibit employers from scheduling full-time workers for 7 consecutive days. Similar laws throughout the country prohibit 7-day work weeks, or require employers to pay overtime to any worker who works more than 6 days.
There are some exceptions to the 7 day rules based on the nature of the job. For instance, according to Deskin Law Firm, if the nature of a job requires workers to work for more than a week at a time, the worker must get the equivalent number of days off in the calendar month. So, if a worker works for 15 days, they get 2 days off to make up for the 2 weeks that they didn't have off.
