It is very different week days vs weekends too. Mobile connectivity is part of the answer, especially in the US - but more over businesses tend to have crappy network connectivity which is perversely small-C conservative and that means lots of them are still doing IPv4 even when that's directly contrary to their own needs.
Corporate networks tend to have a lot of local policy, and so that's a maintenance burden that probably nobody is paying for so it's just a growing debt for the organisation. Even if every policy was excellent when it was deployed many of them probably hurt by now. At home that stuff tends to get flushed periodically but medium-large businesses have processes to preserve the status quo. The same underlying mechanism that prefers to terminate the 25 year secretary who "made fuss" about a VP putting his hand up her skirt rather than do anything about that senior executive will also prefer to buy $5000 Cisco switches and then disable everything that makes them better than a $50 Costco switch over just buying the Costco switch (let alone using the features of the expensive switch). Change is seen as bad and must be prevented.
This hurts for security a lot too. There's a very good chance that accessing work email from a work laptop in the office is meaningfully less safe than accessing GMail on your phone in a random coffee shop because of such policies.
