I am about to be a college graduate and I am applying to new jobs. I currently have an offer from the company I am at right now and have accepted it, but I do not want to stay at the job. I am applying to other opportunities to find something that fits my career goals more. On the application there is a question requesting permission to contact supervisors but I do not want my current employer to know I am looking at other opportunities. Can I put 'no' on the permission to contact? Does that hurt my chances, even if I explain?
