Yebbut, there's consent, and there's consent.
As a long-term inmate of the oil industry, I can tell you exactly how consent works.
For example, the Working Time Directive.
The UK successfully battled for the right to opt out of this, on behalf of all the Hard Working Families.
We got the 'right' for employees to consent to work longer hours.
Yay for worker's rights and choice.
Right.
Actual effect?
"Sign the opt-out and continue your long hours, or sling your hook."
