That's why flight attendants make up a disproportionately large share of the turbulence injuries.

F/As move about the airplane during turbulence everyday. They get pretty good at it and they develop experience from which they can judge what they can and can not do under the current conditions. They will frequently make the decision to delay service and often consult with us on when their best opportunity for service will be.

If the conditions are stable, i.e. we not expecting an escalation of the turbulence, and it is not moderate, or more, we will often allow the F/As to continue what work they are comfortable to do in those conditions. That doesn't mean that it's safe for passengers with little, to no, experience moving about during turbulence. We can not rely on the passengers using their experience to make their own judgement calls as we can with the F/As. We have to keep them safe. That is our responsibility both legally and morally.
