We have that too in our production, although it isn't down to the individual. It is pretty extensive monitoring by line mainly for situation where things go wrong. Sure, there could be a case where the chemistry between line worker and manager doesn't work out. I think these cases are rare and people must find alternative arrangements. We must be productive since we produce in a first world nation on an international market and line workers are low wage workers, no illusions about that. We can calculate needed material and expected output. We plan with that. If that is reached, we have succeeded. People help each other when things go wrong. Far better than a mediocre developer fantasizing about KPI and making stop watches for people taking a shit. Obviously creating a condition where workers are competitors might be a hindrance here. No wonder your factory sucks on productivity, everyone is a adversary and if others are slower I will look better on performance sheets. Genius management approach.
