Pursuant to Nevada Revised Statutes section 608.019 an employer must provide a minimum of a 30-minute uninterrupted meal period, for a continuous 8 hours of work.
It is not legal in the US per OSHA regulations for an employer to work an employee 8 hours without a scheduled break. In fact, the OSHA rules are to be posted in every break room.
In the state of Nevada, an employer shall not employ an employee for a continuous period of 8 hours without permitting the employee to have an uninterrupted meal period of at least 30 minutes.
Breaks are not required at all in Illinois. However, if an Illinois employer chooses to provide a break period, they must be counted as hours worked and compensated if they last 20 minutes or shorter.
If your employer failed to provide those breaks, they may be violating Nevada's labor laws. You could consider discussing this with them or filing a complaint with the Nevada Labor Commissioner if you feel your rights have been violated.
(a) Every employer shall allow every employee except those specified in this Section at least twenty-four consecutive hours of rest in every consecutive seven-day period in addition to the regular period of rest allowed at the close of each working day.
You can either sue or file a wage claim with the Illinois Department of Labor. Employers are required to provide at least a 20 minute break within the first five hours of work, so long as your shift is at least seven hours long.
