Who would want that? The US style is the best of both worlds IMO. By cutting you off immediately the company protects itself from rogue employees who may try to harm the company while their access is still enabled. For the employee, being cut off means you don't actually have to do anymore work for a company that's letting you go. You're either getting severance or you aren't, and I'd much rather collect severance while not having to work. In the instance that they're letting you go without severance: yes that's horrible they just pulled the rug. But usually that's a result of poor performance and you probably should've seen it coming. And frankly that's also why we have unemployment.
