Zero growth can also mean that it is not possible to be more or less efficient. If labor efficiency is not correlated with productivity - then there may not be any economic incentive to well organize labor. As an example - historically agricultural productivity was not a question of labor organization, or labor efficiency. A farmer could only grow but so much food with the land aloted, available water, and crop/fertilizer technology of the time. This amount was relatively close to subsistence. The sowing of crops could be made more efficient in terms of person hours. But, without a production surplus, and no additional land to cultivate - there wasn’t much else for the individuals to do with the surplus hours. Similarly, in a modern society labor productivity can be decoupled with economic output.
