This is no blanket 'thou shalt not call thy employees after hours' law.
All this is doing is preventing employers from effectively pulling a bait and switch, by implicitly expecting employees to be available 24/7 for whatever reason. If you've ever been in a situation where your boss just fucking calls you because of some asinine reason ("hey I just had an idea...) then you know how terrible it is. Nothing spoilt my weekends as much as a boss calling and I'm thinking "o shit prod is down" or whatever, and then it's just him asking on a delivery date for a feature because he's having drinks with the client now and they were asking.
Now, if there is a requirement for after hours availability, it has to be stated in the contract, and the compensation must accordingly reflect this additional requirement.
I think it's great this is happening.
