Do PEO's cut corners? This employee thinks Trinet does.

Matt of New York, NY on May 3, 2011​My employer uses the PEO TriNet to handle our insurance plans, payroll and general HR requirements. I used TriNet’s on boarding process to choose my health plans, and then confirmed that the health plans I chose were processed by TriNet. However, TriNet never on boarded me onto my health plan (Aetna), and when I called TriNet, their explanation was they just didn’t do it. Would I like them to try again? TriNet had this same issue with other employees at my company. My impression is that TriNet has poor attention to detail and may be cutting corners.
