If someone working is making mistakes, first ask why? Don’t just chase
what’s on the surface—rather, always go to the root cause first. A lot of
productivity issues result from a worker’s lack of knowledge or training.
A worker can’t let on because people will think they’re incompetent and
they’ll get into trouble or possibly be fired. But if you’ve built trust with
your respective workers, then they’ll feel free to admit when they’re stuck.
