They had to work harder. They started working 60 hours per week. Then they had Sunday afternoon work too. It was "voluntary" but if you didn't go, you got your food ration cut in half. A lot of this work was being done to try to rebuild the windmill.
Even then, things got worse. The crops weren't producing as well as they should have. This was because they had not had time to do all the work needed to get them ready. This meant that it was going to be a hard winter.
So, they're having to work harder and yet they still don't have as much food as they should have had.
1. All that year the animals worked like slaves.
2. Throughout the spring and summer they worked a sixty-hour week, and in
August Napoleon announced that there would be work on Sunday afternoons
as well. This work was strictly voluntary, but any animal who absented
himself from it would have his rations reduced by half.
Both these quotes from Ch.6 testify how the animals had to struggle in order to keep body and soul alive. Further the task of building the windmill "was a slow laborious process," because the animals had to break the stone from the quarry into suitable sized pieces by first hauling the huge boulders to the top of the quarry and then toppling them over the edge to break them into smaller pieces.
In Chapter 6 of the book Animal Farm the animals have to work 60 hours a day. It is supposed to be voluntary to work the extra hours but those who do not work will have their rations cut in half if they don't work and support the community. Their harvest is not as abundant as they had hoped and it will be a hard winter.
The animals begin to see their limitations as they do not have hands that can grab up picks and axes but they have hooves. They can not operate the windmill the way they had hoped. To break the large boulders they have to tie ropes around them and trudge uphill. However, when they drop them they do not always break, and they have to start over again. The work is very tedious and difficult.
