former call center employee for an outsourcer
Maybe i'm just lucky, but the company I worked for was well regarded by our clients and participants. We handled medical/pension/401K plans for private employers. When I started it was a US company, after the great recession, we were sold to a Dutch company. From my POV, things got better. Any time I entered a file there was a record of what I did/info viewed.
My advice, read any doc you get about your employee benefits.And if you can run a diff on them .Perhaps one of the many more knowledgeable commentards can show how to do that.
