Vantaggi
Being a member of Interactive Data before its two purchases to become part of ICE I believe that the Positive is that it is a company with a single focus on being the best and biggest. With that comes the annual bonuses which were good.
Svantaggi
ICE is a highly charged stop for no one company and targets set at very high level appraisals become mountains for the underlings below. Coming from the FT Interactivedata days to the ICE days I saw how staff went from being valued people to dispensable commodities. Contracts have only one constant and that is your name, everything else is written in such a way or interpreted to get that last pound of flesh from you. I saw a share scheme introduced and sold as a compromise for extended hours taken away the next year. We had to follow a 3 year glide path to reach parity with other staff after being purchased and therefore robbed of parity in bonus rewards.
