Pros
Lots of vacation time, opportunities to work remotely, they care very much about the community, relaxed/no dress code (from the CEO "dress to your day"), many employees who are from CT love working in the Hartford office, CEO is very forward thinking and progressive and has made a big effort to improve company culture
Cons
If you're thinking of moving to the Hartford office and you're not from CT, I don't recommend working here. Almost everyone in the Hartford office is from CT and they are not very welcoming to other views or cultures. I've talked to multiple people who have worked in other places across the US and we all had culture shock when we started working for Travelers. It's very much "their way or the highway" and they will purposely make your job miserable and refuse to promote you in hopes that you will leave their team simply because you have a different cultural normal for corporate america.
