Pros
Reputation, benefits are decent still but nowhere near as generous as before the merger. Benefits start on first day.
Cons
Company was great when it was Willis. Since the merge with Towers Watson, it has been years of chaos and constant change, lay offs, reduction in benefits, bonuses that are less each year despite continued good performance. More and more is getting offshored to cheaper countries and a lot are losing jobs. Those who are "lucky" enough to stay end up doing twice the work for the same salary and a smaller bonus each year. It has become painfully obvious that the new Willis Towers Watson only cares about how much money they can squeeze out of a dollar, and the attitude toward employees is becoming more and more callous and sterile. I do not recommend working here.
