Everyone has their own explanations for why businesses do these things, and I see merit in many of them. Here's my contribution to the list.

All these complaints about poorly-thought-out RTO policies come from big corporations. If you're a senior leader in a organisation with tens or hundreds of thousands of employees, it's very difficult to keep in touch with the people who actually do the work in making or providing the product or service that the business brings to the market. As a consequence, leaders come to believe that the routine of their work day - ingesting reports, engaging in discussions, and communicating decisions - is representative of what's going on in the organisation. Ultimately, I think it's a limitation of human psychology: the organisation is larger than Dunbar's number, and so starts to become opaque to its members.

My solution is to only work for businesses that are small enough for everyone to know everyone else.
