The organization is admirably improving its staffcare support, but it is still not enough, especially for people who work overseas in conflict environments for long periods of time and need psychological support as they reintegrate into DC--or equally often, move on to the next high-threat post. The agency offers extended support to people who return from Afghanistan, Iraq, and maybe Sudan, but its policies don't keep pace with the speed at which other posts unravel and present even greater mental and emotional challenges (and damage) than these much more established posts where the US military is/was providing support. We are way behind the Military in our efforts to support people who risk their lives and safety as much or more than even some DoD employees who do not have jobs that require them to leave safe zones in the countries they work in--and who are trained to work and be safe in those environments. Also, benefits vary drastically depending on whether you are a USPSC or a direct hire. My list of benefits offered/not offered below is from the perspective of a PSC.
As an intern you will not be eligible for health benefits but you will be able to telework if you have a good relationship with your immediate supervisor.
