That's not how European courts have been interpreting it. When they say "free consent" they do mean free as in beer, so a "consent or loose your job" provisions would almost certainly be thrown out.

In the UK, to pick a specific example, it is a combination of some workers not being allowed a choice of opt-out (e.g. healthcare workers, self-employed, "gig workers"), some union workers derogating that right to their unions collective bargaining... but for every other worker, the 48 hours is the law. You cannot mandate it in a contract. You can't advertise a job where you set the hours and those hours are on average over 48 hours per week. It's not a valid job and you are immediately in breach of statutory law.

You'll have to look at member states cases, it's on them to define how the opt-out works.
One example: https://assets.publishing.service.gov.uk/media/61123e81e90e0... "In respect of the 48 hour week the claimant had not signed an opt out and as such if the claimant was working in excess of 48 hours average across the week then her right was being infringed. It is not in dispute that this is a statutory right capable of protection."
