They were paid market rate for hte value they bring to the business, that is true. But ... did the contracts they signed stipulate medical care coverage? If not, why not? Yet they signed the contracts anyway. Sounds to me their respective agents should’ve pursued that little detail.
And..their medical care they received with their respective teams is far and away what common folk receive.
I don’t know what the contracts say. As far as I know it doesn’t matter. They are doing a job and if they get hurt at that job its the employers responsibility.
I’m sure its not that clear cut since the owners have so many lawyers but I know I’m responsible for any employee or contractor who works for me.
The medical care they receive from the team is primarily focused on keeping the on the field, not their overall health.
