Tenants' rights only vest under rental agreements. It sounds like you have at least an oral rental agreement for the room in which you reside in exchange for your labor. The answer to your question is definitely maybe. More information is required. In order to better assess your status, I would want to examine every piece of paper related to your occupancy of the room(s) as part of a more in-depth investigation which may also include interviews of potential witnesses.
Since your immediate concern is not getting evicted before you have found an apartment, you should definitely keep looking for that new place. I think it would be wise, though, to carve out some time to meet with an experienced landlord-tenant attorney for a consultation (if you go through the Oregon State Bar Lawyer Referral Service (800-452-7636; http://www.osbar.org/public/ris/ris.html), you cannot be charged more than $35 for a half hour consultation).
You may also have wage claims, since you are working more than you bargained for. You'll have to be able to provide some evidence of this, so make sure other employees, contractors, or customers can be witnesses to your labor above and beyond the rental agreement. Ask the Lawyer Referral Service for both a landlord-tenant lawyer and an employment lawyer if you call them.
