The only saving grace initially, should you make it through the expected layoff for the duplicate positions from the merger, is that NatGen leadership is heading up the transition into Allstate. Some of the initial good work conditions and environment you enjoy should remain for at least a little while especially while working from home.
However it is only a matter of time before the good hands land of toxicity takes over. Eventually you will be input into a world of Transformative Growth, two faced management, vile office politics, and horrible morale that will only s— the life out of you. Allstate is a sinking ship of pain and despair. The reason Allstate purchased NatGen is to buy market share because Tom Wilson and Glenn Shapiro are not competent and unwilling to grow market share through process and initiative changes.
I wish I could paint a rosier picture but it just isn't possible without flat out lying to you.
