Yes, it is. Though you'll more than likely see returns much higher than a standard (but safe) savings account will give you. You'll also get that 2% float on top of free money.
2% still isn't bad. Free is free, as I said.
In my particular case it's only 5% (best case):
50% match up to the first 10%.
So if I contribute 1% of my pay to it, I'll get a .5% match. If I contribute 10% to it, I'll get a 5% match. I can contribute more but I'll only ever get that 5%.
In your case, this is good compared to my situation in that you don't have to contribute 4% to get that 2% match, you can contribute even just 2%.
This is in the US FWTW. It's a pre-tax situation. I don't pay taxes on my contributions or my employers contributions; but I do when I withdraw them (earliest I can start withdrawing is age 59-1/2. The assumption is that when I start withdrawing, my tax rate will be lower than it is now so I'll still "come out ahead".
Also the country is Thailand, so there might be differences.
