A discretionary profit-sharing contribution of up to 3%, with lots of fluffy language meaning they can easily get out of paying if the company does not do well. Or if they feel like it, I guess, although admittedly they only cancelled it in 2008 and possibly 2009 as far as I remember. They used to have a small match as well which was cancelled at the same time and will not be reinstated.
They pay out twice per year, although if you're part time like me, you only get paid once a year as you have to have worked enough hours to qualify and I usually haven't qualified at the time of the first payout. Also, the second payout is for work up to 12/31 but often doesn't get paid out until the following July (it used to be January, but the last few years they've delayed). I asked what would happen if I left between 12/31 and the payout date, and got some vague comments that they would pay it but I don't necessarily believe them.
