factor of forever
the owners are always on the watch for a raid. there have been many, so they have methods in place to protect themselves. they are only held accountable if they are literally caught in the act of having a child employee working, so they have hiding places for the youngest if a raid comes.
victims rescued from one factory told me of large barrels nearly full of waste water into which they would climb to hide, learning how to tilt their faces just so, accessing the small pocket of air between the top of the water and the lid to the barrel, while still allowing it to close. "no one touches the barrels, so we wouldn't be found", they told me.
after the raid they would crawl out, unable to shower, often to be beaten for the work time missed while they were hiding. hiding so their owners wouldn't be arrested. hiding so they could continue to pay off the interminable debt incurred by their family. by their existence. debt with interest rates of 200-300%. debt that meant a one time pause for breath in and out was another 3 seconds not working. 3 seconds on 300% interest...each breath prolonging the time to payoff by a factor of forever.
