I'd start looking for another job just in case. It is far easier to find a job while you still have one then after you lose the existing once, especially if you are unemployed for a while. Take it from someone who was once in a similar position. I wish I had started looking for a job when things started getting bad, rather than just try to just hold on and hope it would work out.
This is especially true if you are in an "at will" state, where you can be fired for any reason, and for none at all.
