Is it possible to accrue vacation hours during graduate study as a research assistant (GRA)? I currently work full-time for the Department of Defense.  I usually get three-weeks worth of paid time off every year.  This has been helpful because I like to go back home to visit family for about two weeks or take a long weekend and visit friends around the country.  

I will be starting my master's degree program this coming fall and I have managed to obtain a part-time graduate research assistantship (GRA).  In reading the student handbook, I noticed that GRAs are required to work year-round and only allowed to observe certain holidays.  There is a provision that you can work more hours over several weeks in order to get some consecutive days off.  

My question is, in the graduate student lifestyle, is my dream of maintaining 2-3 vacation weeks a year completely thrown out the window?  Will I be expected to stay on campus and work every single possible day?  Do GRAs grant vacation hours that you can accrue?

Thank you for your time.
The answer is: it depends.

The biggest factor is where you're a graduate student. For instance, graduate students in Germany receive up to six weeks of vacation per year, while graduate students in the US may only get two weeks' vacation per year, if even that much.

However, I think that in the US, where policies are a bit less generous, the real deciding factor is your graduate advisor. I think that reasonable graduate advisors will permit students to take off a few weeks per year (especially since most of them might do so themselves!), provided that you make sure it doesn't conflict with any major deadlines or events in your group. For instance, asking to take substantial vacation time just before your first big conference is probably inadvisable. But time during the holidays or during a relatively "quiet" time in your group (whenever that happens to be) would probably be OK.
