What would happen if a slave passed out during work?

If a slave passed out during work, it could lead to severe consequences. Depending on the circumstances, they might be punished for perceived laziness or disobedience, or they could be left to recover without assistance, which could result in further health issues. In some cases, an overseer might intervene to ensure the slave's recovery to prevent loss of labor, but compassion was rarely a factor in such decisions. Overall, the treatment would vary greatly depending on the specific slave owner and the conditions of the work environment.
