The PhD Plus 10 Study was the first-ever follow-up of mid-career physics PhD recipients. In 2011 individuals who graduated with a physics PhD from the classes of 1996, 1997, 2000, and 2001 in the United States were contacted. Of those who responded to the survey, 597 were employed in academia, 464 academic employees worked in physics or astronomy departments at four-year institutions, 106 worked in other academic departments at four-year institutions, and 27 worked at two-year colleges. In this report, the author focuses on three groups: (1) respondents employed in physics or astronomy departments at four-year institutions; (2) respondents employed in departments other than physics or astronomy at four-year institutions; and (3) respondents employed at two-year colleges. In this report, the author describes the activities that academic employees perform during their work and what they find rewarding about their positions.
