You don’t need permission to rest, but you might need to schedule it.

Nobody is really withholding permission. The obstacle is structural: rest has no start time, so it loses to everything that does. Practice has a time, the shift has a time, the group chat has a time, and the hour of nothing gets whatever is left, which is usually nothing. Protection comes from a slot, not from feeling entitled to one.

Give it a time this week the way you would give practice a time. Thursday from four to five, no task attached, phone in another room. If something tries to move into that hour, treat it like a request to skip training.
