It's not clear, because the details don't exist yet. There is only a directive that requires the member states change their national laws within a few years. There will likely be at least 27 different interpretations of the directive, which will all evolve in response to the specific circumstances in each member state. Many countries also have informal mechanisms of enforcement. For example, businesses may have learned that it's often better to comply with the spirit of the law voluntarily. That way the final regulations will be more flexible and reasonable than by forcing the government to spell out the details explicitly. Or there may be strong unions, in which case many issues may be effectively decided in discussions between unions, businesses, and the government. If businesses burn too much political capital on a minor issue, they will have less influence on bigger issues.
