They could come to an agreement, sure. But that's not Jack standing himself down.If Jack was not in the right mental state of mind and asked for time off i cant see the club not paying him
Imagine walking into your employer's office and saying "hey boss, I've been charged with rape. It's making me stressed, so I've decided to stand down from my position. I'm doing this for the good of the company so you'll need to keep paying me while I'm on leave".
I just can't see it playing out that way. Jack could agree to standing down in agreement with the club. But can't stand himself down.
