Aha, here you are!
Bakewell
Bovine/ovine slaughter
Easy to spread out. Bigger animals in pens for lairage (pre-slaughter holding area) so maybe 2 or three people there, including a vet, to check animals on unloading, move to pens, but can keep apart.
One person to move animals up the race, one in stun box. One for shacking, one sticking. So again, distance separated, then the animal is on a rail and you have one person performing each step, so legging, hide pulling, evisceration etc. For lamb, they are usually standing, for beef they are in little caged platforms that move up and down, so automatically separated.
Carcasses move into chillers on automated rails.
The move on rails to cutting area, with one butcher making each cut. At the packing end it can be a bit more crowded as you have people either side of a conveyor lifting "their" cut off and packing in bulk boxes.
Retail packs are normally done at a different facility.
Storage and despatch is fork lifts, so again, easy to separate. Less people at these facilities, easier to stagger breaks. Usually change clothes each break, particularly at the killing end as it can be messy.
Chicken arrive in large crates (modules).
Unload by FLT, then two people needed to lift each mod into lairage. Birds don't come out of mods.
Two people required to lift mod to shackles. Multiple people required to stand close together and shackle birds. Small animal, high throughput, fast lines.
The Anglesey plant does KFC so will be Halal. Automated line through stun bath, then maybe 4-6 people to do throat cut due to speed and halal can't be rotating knives, has to be by hand. All close together.
Plucking and evisceration is automated. One or two people to remove livers, hearts, gizzard from pluck. Close together.
Various people packing whole birds. The line grades automatically be weight so people standing close together to grab the corrects birds for their box.
Cutting area has a conveyor with people each side either cutting or packing. Small animal so belt not very wide. Far more people and close together.
Chicken plants are cramped with a lot of rails close together. Require more people. Difficult to stagger breaks as you don't have enough cover on the line if you send small groups.
This is why the chicken industry is higher risk
