When the seatbelt signs go on for turbulence, the cabin crew have to make sure that pax are seated with seatbelts fastened, infants on laps are also strapped in and that the toilets are empty. There is no requirement for the crew to also take their seats and strap in, unless the Flight Crew request it or if the crew feel that it is too dangerous for them to move around.
The legal definition of cabin secure for landing is passengers seated, cabin secured and crew in their jumpseats ready for landing. This same definition does not apply for turbulence.
