Taking Their Place
The brave worker decides to station himself in the most dangerous location to ensure the safety of the others. Then two more brave workers decide to pull on the snake’s tail in an attempt to stretch it. While they were doing this, luck was on their side.

The head is quite a distance from the tail’s end, so the chances of it biting them are slim. Especially given how slowly the snake had previously moved. They still don’t want to take a chance, so they take extra precautions.
