Can I require non-exempt staff members to change from working daytime hours to evening hours as long as they don’t work more than 40 hours per week?

Yes, you can adjust the work hours of an employee to meet the needs of the department. When possible, advance notice (a minimum of two weeks), of such changes should be given to the employee. You can rearrange hours within the same week, but the regulations do not allow you to move hours from one week to the next. The determination of 40 hours “worked” must also include vacation and sick time, per administrative policy 6-07.9.
