Erica,
Sometimes refered to as soft skills, attributes of appropriate language and spelling, dress and grooming, behavior such as courtesy, and professional readiness such good attendance and punctuality often make or break a new employee. Less so is the technical skills in a job, but more so is the basic "just being there, on time, relating professionally to coworkers. More people are let go because of these very correctible traits than the technical skills that are a part of the job.
