Am I the only one who wants to work from home and still get the 30k-a-year raise? jokes apart, if remote culture consolidates with different compensation and benefit packages compared with those in the office, we'll likely start to see lawsuits in that matter.
If employers feel employees working from home are less valuable, and employees prefer working from home, it sounds logical this will results in lower compensation for WFH employees. Not sure what laws they would be breaching here, it's just the market at work. It doesn't even matter whether they are right or wrong, the market should take care of that.
