In the case of Spanish crews, this is to be decided in court probably at the end of the summer. Having said that, a favorable sentence of "direct employment" as you called it, would only mean that norwegian is liable for the expenses associated to redundancy packages and not necessarily that they're going to keep the crew. It's just that it won't be for free.
What's important right now is that norwegian remains alive and that it's able to ramp up slowly but surely. For this small increase in the summer, only crews from Norway will be brought back to work, which is a little start.
