While it's gone unnoticed by most, Staples quietly renegotiated you 401k's a while back. That's NOT news.Companies do that ALL the time.
However, what is news is that they dropped a Money Market cash account option. Simply put if you want to protect your gains, or feel that the market is in jeopardy, you have ZERO option to move your earnings to a safe harbor. Now MOST 401ks offer a money market option, so why would Staples eliminate that option?
Follow the money folks. They are not in this for the employees welfare. They care ZERO about you protecting your retirement funds. They care ONLY about protecting themselves. FOLLOW THE MONEY!
