I've been interviewing with a staffing agency for many of their open positions that they have told me about. One recent one was a contract-to-hire role and they asked if I was okay with that. I stupidly said "yes" not thinking about the ramifications of health insurance, potential that I don't get hired after the contract, the fact that it's hourly (not salary, which I prefer) etc. It turns out that I am being offered the job, but don't want it due to the reasons stated.
How can I minimize bridges burned with this staffing agency? Many of their positions seems great, but I am regretting telling them that I would accept a contract position.
