Most factories practice two modes of compensation: 1. Per pc rate - Payment is directly tied to the output, more efficient. Requires skilled workers and can sometimes be a little costlier and impractical. Defects are deducted from the workers pay.
2. Monthly salary - This setup can accommodate semi skilled workers since each worker only handles one part of the whole. It’s a relatively cheaper process. However inefficiencies can easily creep in, defects can pile up which can wipe off the whole margin and ruin the factory.
I don’t believe in running a sweatshop, but even well run humane factories have to battle inefficiencies all the time. The line between marginal point inefficiencies can mean canceled contracts, cancelled goods and financial losses. At the end of the day it’s the workers who have to take the brunt. The upside of efficiency is timely wages; the downside is already obvious. The upside of inefficiency is a little break for workers; the downside is job loss and unpaid wages.
Hence I am not a fan of mass production esp under contract from Big retailers.
