Hmm ..the irony is that jobs that require the least amount of credentials have the least accommodations. White collar jobs, especially in tech, seem to have so many accommodations or delays and extra time. Think how often employees come in late or delay work. HR exists to accommodate these requests. College, and school in general, has far fewer accommodations and flexibility than seen in most work environments, save for low-skilled jobs where puantiality is necessary.
Like if you work at an assembly line making widgets, the upper bound of productive work you do is proportional to the time you're physically there, so in this aspect it makes more sense for the employer to use that as a metric. In contrast a lot of tech jobs can be done remotely, sometimes if you're trying to solve a particularly nasty problem you don't even need an internet connection while you're thinking deeply about it.
