      Pros

      local manager Nicole Michalczyk is fantastic to work with. The ESS org overall is well run with great tech tools to accept or decline assingnments easily. Nicole also is great at sending reminders regarding benefits available to employees and also offers lots of 'spiffs' to engage staff. Working in the city of Nashua public school system has been fantastic and eye opening. Teachers and Admin staff overall great and I've worked in may of the schools!

      Cons

      The ONLY con is that school budgets to pay subs is pretty low, but understandable considering budgets across the nation for public schools are tight! There is a funding problem for schools in general across the NH and the nation - this is not an ESS issue.
