Insurance is really good and the employee contribution amount is fair.
After 30 years, the pay is too good to pass up.
They are forward thinking and distribute profits to employees through bonuses in a fair way.
The morale is good for the most part. People are paid fairly and that helps to keep morale high.
It was a very long time ago and the company I interviewed with was Arkansas Freightways, which was eventually bought out by FedEx.
It has changed over the years, but aside from being overly concerned with being PC (I think that is how all companys are now), people feel they will be heard when they have concerns.
