It works both ways, if they want the same rights as other workers lets see if they are willing to take the same wage as other workers.
I look forward to Ronaldo being told that hes no longer on 250k a week and see how much he can cope with 30k a year.
Its nonsense.
The footballer contract can have an exclusivity clause.
Meaning that the player must have permission from the club holding the contract before playing for another club.
They can then put in place a confidentiality clause to back that up. Meaning the player can't take confidential information with them to another club without permission from the contract club.
Good luck with that one because they are legal and enforceable in the civil courts.
Players could end up sued by their former employers.
