Once again Fortune has published it's list of the "Best Companies to Work For".  Fistful of Talent had an interesting  post about the "dirty little secret" that exists within almost all companies – those on the list and those not on the list.

But, hid inside the underbelly of these environments is a dirty
little secret.  The dirty little secret also applies to companies not
listed as well.  I'll outline it for you two ways – one for the "best
companies to work for, and one for "the unwashed masses".  It goes a
little something like this:

–The golden rule – "A company's culture and attractiveness
as a place to work is contingent on the effectiveness, approachability
and progressiveness of your manager.  That means:

1.  A company often listed as a great place to work is often mocked by those within the company with an ineffective manager, and

2. A company not listed as a great place to work will receive many of the same retention benefits among employees, who have a great manager who reinforces, supports and leads.
