Good matching 401k, 90% paid insurance, awesome profit sharing program, everyone participates in strategic thinking, and the best benefit of all is the incredibly delightful and fulfilling team spirit and engagement.
I suppose the best thing about the benefits package is the vacation. However, the fact that we're small enough to take everyone's unique situation into account when strange things come up (something that is hard to show in a checklist) is even more valuable.
Best thing is Vacation plan.
