Much of what is out there is a "401 match." The employer will match a percentage of your salary that you contribute, usually 3-5%, but sometimes more. How you invest it will determine what sort of growth you get with it. Learning to invest takes a bit of research, as well as the ability to take risk. Those who refuse to take that risk often times earn less on their money than the rate of inflation. That means that, over time, the buying power of their money decreases, rather than increases. I am not an investment advisor. Generally speaking, the younger you are, the greater risk you can take, because you have enough time to be able to recover from it.
Government agencies still offer traditional pension plans. But these plans hit on hard times, and we see them changing the terms. For example, instead of retiring at 60, perhaps they require employees to wait until age 62 or age 65, but don't make corresponding increases in the pension amount.
Some employers offer other options. For example, some companies give employees stock.
Beyond retirement plans, you want to look at the total value of the benefit package. Health insurance can vary drastically from one employer to another. Vacation time is also a benefit that is often overlooked. Also, if you want to go to school, an employer tuition assistance program will help considerably.
Also look at tax-deferred options. For example, if you can set aside part of your paycheck, tax-free, to use to cover medical costs, that will save you money, as you never pay tax on that part of your salary.
Good luck as you start down this path - it will all make sense after a while!
