The National Labor Relations Board (Case 1-RC-20574; In RE: Housestaff of Boston Medical Center) ruled that medical residents are employees under the NLRA. They state specifically that residents "therefore are entitled to all the statutory rights and obligations that flow from our conclusion." This case, was about the collective bargaining rights of residents, but the statutory outflow would appear to indicate that residents are to be considered employees under the Act. And, if you are an employee, then you should be paid for your time that your employer has demanded of you, in my non-legal opinion.
Mass, Maryland, California, Michigan and others have recogized this and residents are covered under their state statutes. In these states, the state considers you an employee. I suspect if you have federal income taxes, FICA taxes and state income taxes withheld you would be considered a statutory employee for the purposes of wages and salaries.
The Labor Board recognizes two distinct categories of employees: exempt and non-exempt. The exempt employees are exempt from overtime reporting/payments and are generally ungraded/professionals who do not get paid overtime. These are called salaried workers.
This would be the category that residents fall into. The other category are those who exert no control nor supervision and independence over their jobs. These are non-exempt and are owed overtime in accordance with federal law. These are also colloquially called "hourly" workers, such as nurses.
To the best of my knowledge, NY is one of the states that the labor board considered, and I think NYU was one of the hospitals that was involved in the original labor board decisions, along with BMC.
I was paid for my orientations, both transitional and residency (4 days in one case, 2 in the other, mainly to do the drug screen and get computer passwords and such). When I first heard that there were programs that did not pay for a mandatory "orientation, " my first thought was hokie sox, this can't possibly be true. But, alas, it clearly is. Are there no depths to which hospitals won't sink?
A program that does not pay for orientation, because the law says they have to or otherwise, in my mind merits a DNR on the ROL.
