High quality insurance without terribly huge deductibles, although scheduling vacation time can be difficult and feel like a burden.
Standard but also provided 401k.
Unlimited sick days and free events
The best thing is that they offer them, though what they are, I wouldn't know - see my next point. The worst thing is that they don't offer them to full time employees that are staffed as "Temporary" assignments. Seems a little unfair that even at a salaried level I should be paying for my own insurance out of pocket?
Good health coverage & 401k, they provide some transit help, but pretty strict about vacation days and PTO.
*15 days PTO, unlimited sick days, 3 personal days=great benefit
There aren't many perks for part-time employees other than the discount on clothes.
