there's a robber baron era term for this and it's called the "stretch out" - here's some background https://www.newsandpress.net/the-stretch-out-the-idea-that-wrecked-life-for-mill-workers/

• I remember many conversations about the stretch-out system and the way it was operated in the big mill where my Dad worked. As my brothers reached the age when they were old enough, or should I say, “big enough,” they too told stories of the stretch-out. By the time I was old enough to work at the mill, much had been changed. The child labor laws were in effect along with the 40-hour workweek and eight hours per day. In the book “Like a Family,” the authors share many stories about the stretch-out and the effects it had upon the textile industry throughout the South. Some results were devastating, even resulting in deaths in some locations. The things of which I write are those that I experienced and witnessed while living on the Mill Village in Darlington. Let me begin by saying that it was the stretch-out system that led to the closing of the big mill, Darlington Manufacturing Co. in Darlington. Yes, I know that the final straw was the unionizing of the mill in 1957, but long before that, a promise had been made. Now, back to that time long ago. I recall sitting on the Atlantic Coastline railroad track and watching the long line of mill workers parade by. A walkout had been called by their leader, and workers left their jobs and followed! They were protesting against working conditions that had been imposed by the stretch-out system.*

A few examples are given here. Young men were hired to follow workers on their jobs or stand nearby with stopwatches in their hands to determine the minutes lost by workers. For example, if a thread was broken on a weaver’s loom, that worker stopped the loom to tie the thread, and then would restart the loom. The stopwatch recorded the lost time.

If a worker stopped for a drink of water or to eat a sandwich or to go to the restroom, all those minute were added and the time lost was reported. No longer could a worker receive a promotion on his or her job. Young college folk were hired for positions as overseers and supervisors.

quoting the article:

RJ said the Troutdale facility has recently reduced how many tote runners it employs, which means the few people in those positions work harder and stay in the roles longer than they have in the past.

RJ was not near their coworker when he died, but they were at work on April 6. They continued to work until the end of their 3:45 pm break, when supervisors on shift told all employees to clock out and go home, and that they would be paid for the rest of the shift. The supervisors at that point did not tell all the employees someone had died on the warehouse floor. RJ noticed people lingering in the building until 4 pm, roughly two hours after the man collapsed, according to multiple workers.

“Truthfully, I now have even less respect for our leadership team than I did before, which I didn’t know was possible,” RJ said. “It makes me feel more ashamed to work there knowing that people can drop dead and we have to carry on knowing it doesn’t matter to the higher ups, and everyone is replaceable.”
