About the prevailing-wage column. It compares the median offered wage for each role with the median DOL prevailing wage for that employer and role. Both medians mix job levels and worksite locations, so a negative gap does not mean any individual case paid below its required prevailing wage — it describes the mix of filings, not compliance. See our disclaimer & terms.
