I was an Associate Director in the Global IT department.
Pros
I spent 22 years at E&Y and for the most part it was a great experience. Benefits are excellent. I was fairly compensated and advanced throughout my career based my own merit and accomplishments. There is a defined benefit retirement plan, (which is getting very rare in private business) plus 401(k) with match that are very valuable and the basis of a comfortable retirement that I now enjoy. E&Y had very flexible work arrangements, good vacation policies (3 weeks to start), excellent equal opportunities for women, LGBT and all people. I spend many happy and productive years there and am grateful for the experience and proud of my own success and achievements there.
Cons
Business is business. It is a grave mistake to assume that any large business in any difficult financial environment is concerned about the individual employee, but there still may be policies that are beneficial to all employees and that was very true for E&Y. Financial hard times bring swift cost cutting and reductions in staff. Out large global IT department was significantly reduced in the recession in 2009 and many people were laid off, including very senior people, Directors, Associate Directors, many long term employees and older workers, several categories that I fit into and I was also laid off after 20+ years at over 60 years old with very slim prospects for future employment. That, however, was not specific to E&Y. I am realistic about it and because of their good retirement benefits and my own planning for retirement, I was able to truly retire, which for younger people with young families was not the cast. My advice to everyone: be serious and SAVE FOR RETIREMENT!
