Pros
The people I worked with in my immediate area kept me there for more than a decade. If it weren't for them, I would have left in early 2000's. Benefits were really the only dollar associated value that was as good or better than most other companies. Work from home is a viable option for most.
Cons
If you are salaried, prepare to work 60+ hours per week on the regular and you will be given more and more responsibilities with little to no pay increases(2% pay increases year over year were the norm for the last 10-15 years - I should know, I was a director and lead directly or indirectly 100's of colleagues over the years). Work/life balance is preached - NEVER practiced. When my parent passed away I was away for 5 days and came back to all the work that I had when I left, nothing was transitioned and work had piled up. I worked 80 hours the next week to get caught back up and was given little to no support or sympathy from my manager who only cared that I was back to do the work. Emails were sent to me WHILE I was on leave for things to do when I got back which would notify me constantly on my phone during a time where I was trying to field calls/emails from family and friends. This was extremely insensitive and tasteless. When I came back from bereavement leave several of my co-workers informed me that they were instructed to "leave things" for when I got back. The amount of talking behind other colleagues backs was what became the final straw for me. The culture from Aon(which was/is a great company) did NOT translate to Alight and is why this company goes through CEO's like nobody's business. They are on their 4th or 5th CEO in the last 4 years. It's unreal. Other than good, not great, medical benefits - there is nothing going for this company. My final straw was when my last manager informed me that I had to lie to the client about why we failed to meet a service level contractual requirement that would have caused a 10K monthly penalty back to the client. I was told - "inform the client that we met the SLA or I'll find someone who will(you'll be let go)". In hindsight I should have reached out to HR, but unfortunately the HR lead was best friends with my manager, so I felt trapped. It's the good ole boys/girls club there for sure and they will watch out for one another above all else - toxicity above and beyond. Thank goodness I got out and haven't been this happy in my career since leaving. I hope for those that I know that still work there that things turn around quickly with this latest CEO, but it's going to take someone very patient and brilliant to turn around this company.
