What does the law say about meal breaks?
An employee must not work more than five consecutive hours without getting a 30-minute eating period free from work. The employer does not have to pay for time the employee is on a meal break unless there’s an employment contract that says otherwise.
If the employee and employer agree, the 30-minute meal break can be taken as two shorter breaks within a period of five hours. Together the two meal breaks must total at least 30 minutes.
What does the law say about coffee breaks?
An employer is not required to provide any breaks under the ESA other than a 30-minute eating period for every five consecutive hours of work. However, if the employer does provide another type of a break, such as a coffee break, and the employee must remain at his or her workplace during the break, the employee must be paid at least the minimum wage for that time.
