Just be sure to use an investment suitable for an emergency fund such as a short-term bond fund or CD or high rate savings.

+1. Nothing says you have to be in equities or even bonds. Cash for a couple years is fine.
If you do find yourself under-employed for a while, low income years are a great time to contribute to a Roth since the tax impact is low. So keep contributing if you can. Once you are working again, the normal pre-tax 401k/TIRA may be a better place for your savings due to the tax breaks.
