If I have to file a ch. 7, will it make it harder to find a job?

My current field of employment has taken a nosedive due to outsourcing, and I'm afraid I may have to do the Ch. 7 if I can't sell the house before the bills get ahead of me. I'm retraining in a different field, surgical tech, but it will be a year from now before I'm done. I know some businesses check credit history as a means of screening applicants if handling money is involved, but what about hospital positions where handling money is not involved?
