The warden should put them on a hunger strike to go along with their protest strike. They aren’t going to need the energy anyway.
One of the jobs that prisoners do is food preparation & running the chow hall. Don’t wanna work? fine. No work, no sammich. figure out your own way how you’re gonna eat. If it comes down to food this “stoppage” will be over quickly.
Trust me, from what I’ve seen of prison “hunger strikes” this will be short lived. You’re not talking about inherent self- discipline when you talk about convicts.
