      Pros

      I was well trained, my duties were always explained to me. I was never asked to do anything beyond my capabilities without proper training.

      Cons

      The biggest downsides to working at Ceradyne is the heat in the summer, the cold in the winter and the general dirtiness, but it is a factory and Ceradyne always tried to improve condition.

      Pros

      Teamwork, the crew , good pay,

      Cons

      Long hours, forced 12hour shifts with no lunch break and over time, average week is 52 to 60 hours , short staffed regularly, management team not engaged on floor, managers with poor attitudes, no breaks. Promotions are based off of favoritism you will get the interview but they already know who they picked.
