This would be a good opportunity to share and contrast what retirement benefits various companies offer.
In my experience, the two most common options are none and 401K matching.
For IPVM, we automatically contribute 20% of one's annual salary to an IRA (SEP IRA). So if the salary is $100,000, an additional $20,000 is directly deposited into the employee's IRA. Then the employee can invest it as they see fit - money market, bonds, stocks, mutual funds, etc.
