I actually have no issue with clubs behaving like this. Yes it’s not great for the wider game and in an ideal world it wouldn’t happen. But there isn’t anyone pointing a gun at anyone’s head, there is always a choice for players to take a contract elsewhere (probably for less money) and get the conditions they want.
At the end of the day, rugby is a different workplace to what all of us would know, there is zero value in you unless you are on the field. It’s a strange example but what we essentially ask for would be like asking your workplace to go to another workplace for a period of time and potentially coming back with a broken arm and not able to perform your duties correctly but still been expected to be paid properly.
What probably needs to happen is the players in France to unionize and demand a shorter season, but most the clubs are losing entities and expect the owner to clear debts. Until value increases further asking them to play less games and therefore generate less income is expecting them to cover more debt over the year.
