Dear Nancy,

I am an independent nurse consultant for long-term care corporations. I travel to several states (compact license) and sit as the interim director of nursing while these corporations search for a permanent director of nursing. Many facilities are routinely scheduling back-to-back 16-hour shifts (permanent schedules) for their licensed LPNs and RNs. This practice leads to most of these nurses working 16.5 or greater hours and then returning for another 16.5 shift with less than 8 hours between shifts. Is there a maximum number of hours a nurse can work in a 24-hour period? If so, where would I find this information for each state? I don’t feel this is a safe practice for any nurse.

Dear Belinda,

The resources you will need to evaluate the time worked by the nurses in the states you serve as interim director of nursing will be located on the state level. The federal Fair Labor Standards Act (FSLA) does not limit the number of hours an employee can work in any work week if the employee is 16 years of age or older.

Checking with the respective states’ Department of Labor, Wage and Hour Division will allow you to determine what limits, if any, exist for employees working a specific number of hours and any “time off” requirements between work shifts in a given period. This information may be readily available on the states’ Department of Labor Web sites.

Another important source of information would be to determine if the respective states have passed any prohibition on mandatory overtime. Depending on the specifics of the hours worked, it may be that the current schedule(s) violate a state’s mandatory overtime work prohibitions. These laws may also be available on the Internet; but if they’re not, a consultation with a nurse attorney or attorney in each state may be helpful in identifying the existence of these laws.

A third resource would be any scientific data concerning hours worked and their effect on the worker in terms of fatigue, judgment, and so forth. An excellent place to start is The National Institute for Occupational Safety and Health’s Web site <>. On the home page, click on the Safety & Prevention tab, then scroll down the list to the Work Schedules option. Clicking on that option will yield a wealth of information on this topic.

    Given the nursing shortage. Nurses are being made to work long hours and seem to have to recourse. It is unsafe for any nurse to work more than 16 hrs/ day. When and how can we get this changed? Employers are taking advantage of nurses and continue to push the limits regardless of risk to our livelihood and patient safety. Nurses need legal representation and laws and guidelines set to protect us and our patients. I have been a nurse 40 yrs and this issue is getting worst not better. Employers have us over a barrel. How do we fix this and when/ how do we work towards changing this unsafe practice standard?

    I work in dialysis in south texas and we frequently have to work 24 hour shifts due to oncall status. This profession like many other lawyers and teachers is getting worse. Seems like the only thing corporations care about is money and not patient / workers. Thanks Republicans. More rights for corporations and less rights for nurses.
