Ghost jobs! Tremendous dataset. Hospitality and education roles listed near the top are likely strong signal the wages are inadequate and a refusal to raise the wage to a market clearing price. Healthcare is self explanatory, demand is voracious due to a rapidly aging population and wages available and appropriate in many cases.
> Hospitality postings sit the longest: 43.9% have been open more than 90 days, median 65 days. Healthcare turns over fastest at 19.7%.
(kudos to unlisted for aggregating and reporting, this gives me a data point to offer to jurisdictions and regulators interested in compliance monitoring in this context)

Education roles are also an indication of mandatory listing: they have someone internally in mind for a future vacancy but are legally required to list it.
