Guys, you need to read the organisation requirements in Annex IV 'Part-ATS to Implementing Regulation (EU) No 2017/373. I think that it's the' 300 series' organisation requirements which cover fatigue and rostering.
The EU will require ATC service providers to develop a fatigue risk management policy and associated watch rostering system. The CAA plans to publish a new 'human performance' CAP which will include, amongst other items, most of the content of SRATCOH from CAP 670. The plan (as someone mentioned earlier) is that this will act as guidance material for service providers. If they base their policies on the guidance in the new CAP then it gets the rubber stamp. If they want to develop something new then they can but it will be subject to greater scrutiny.
As mentioned earlier, SRATCOH was designed to deal with the Heathrows of this world, in other places it's too heavy handed. The challenge will be for the inspectors to keep an eye on those who might seek to use this as an opportunity for skullduggery.
