My question involves unemployment benefits for the state of: California

I have been laid off for the past three months and have been receiving Unemployment Insurance Benefits as I search for a job. Now the company I had worked for asked me to come in for two weeks to help fill in for the office manager while she goes on vacation. What are my options as far as continuation of my unemployment benefits. Must I accept this two week work under the definition of "suitable work"? If I must accept this temporary work, will I be no longer be eligible for unemployment and re-start the unemployment claim application process for unemployment benefits after this two week assignment is over? Or can I refuse?

Any advice would be greatly appreciated.
