Pros
There are no pros for working for Westat other than you will get paid on time as long as you fill out the most archaic timesheet after you work your 10 -12 hour day, then you'll need to sit down and spend 15 - 30 minutes checking tiny boxes, looking up distances, codes and it felt like a complete waste of time and was tedious as could possibly be. Paid travel time.
Cons
Lifting cases weighing 50 plus pounds, working with people that are completely unprofessional, spending 2 hours plus at the schools in order to wait for all the lunches to get done. Getting to schools in possibly dodgy areas when it's still dark at 5:45 am and not leaving until well after the school closes and then driving 90 minutes. Planning your entire life around your work schedule because it requires overnight stays in motels hours from where you live and paying for all your own meals while there.
