This problem is equivalent to minimizing the egalitarian social cost in the fair division of chores. The two prevalent fairness notions in the fair division literature are envy-freeness and proportionality. Prior work has established that no envy-free mechanism can provide better than an $\\Omega(\\log m/ \\log \\log m)$-approximation to the optimal makespan, where $m$ is the number of machines, even when payments to the machines are allowed.
