You're making my point for me - again. Whether or not she is an employee or simply under contract, if she would have been excused for a physical medical exemption, they should have done the same for a mental health medical condition. Instead, they fined her. That IS logic, plain and simple. It's not knee-jerk at all. It's asking for the same standards to be applied across the board, which they clearly were not. Having a medical emergency is not breaching the code of conduct. It's having a medical event which requires treatment - something that she shouldn't have been fined for having.
One thing we can agree on - this probably is a pivotal moment for the tennis world and the way players are sometimes treated and I think that's a really good thing.
