Our company offers dental plan, one pair glasses or contacts per year and has recently added alternative healthcare to the health plan (I'm impressed by that, though still a little irked that they still don't cover birth control--but that might change since the Bartell's suit, ya never know) But we did add a medical savings plan this year, which helps some.
The company matches up to $1,000 per year on employees' 401K plans.
We also get a lot of "extras"--birthday brunches once a month, a pizza party once a year at the BEST pizza place in town, a yearly holiday party that gets better every year, company picnic, and they've recently taking to planning other special outings such as ballgames, trip to Leavenworth for Xmas shopping, etc. Plus there is always FOOD around here for some reason or other--lunch seminars, donuts, employee meetings--it's hard to stay on a diet here!
There's one extra perk that's provided by our location--a wonderful waterfront view and a great place to go for a walk or sit outside for lunch too!
