Some employers are posting artificially low salary ranges to keep wages from increasing and to avoid alienating existing workers, Bloomberg reported. More companies are disclosing pay ranges in job listings, especially in places like New York City and Colorado, where it is required by law. However, what is listed as the maximum salary may be closer to the middle, according to multiple HR executives and pay experts. Some employers are trying to limit the demands of potential hires seeking top dollar while preventing existing workers from finding out they are underpaid.
