Pros
Liberty is a straightforward place to work, if you've worked at one insurance company, you've worked here. If you just want to come in an pick up a paycheck, without having to return phone calls of claimants, this is a great place to work. Ignoring calls, not returning voicemail, etc are all generally accepted, and your supervisor won't hassle you about it.
Cons
The claims policies are designed to result in a denial regardless of the merits of the claim itself, especially with employer policies that are covered under the Employee Retirement Income Security Act, because even an actively fraudulent denial (which happens daily, by design) won't result in any costs to the company unless a US Attorney decides to prosecute..... which they don't. If that's the kind of place you want to work, go for it - it's safe and secure, as long as you don't mind hurting people already injured and unable to work.
