There is zero, no, justification for H1-Bs in the US. Zero.
For American Corporations - train your people. It’s not even that expensive.
It is hugely expensive.
Currently, one manager in my plant has taken it upon himself to train leaders. It takes most of his time.
The results are great! But our sister plants are saying “We can turn over a new supervisor/process engineer in 3 weeks! IT TAKES IOWA 6 MONTHS!”
Of course, we are keeping most of those trained and our sister plants have 75% turn over year to date, but that is a hard argument to make. Training means you delay having an asset on the floor, and tie up another asset doing the training.
Most managers have no clue how to train people, and no patience for it. Most companies figure that if you hire enough bodies, one will figure it out.
Then there is the often heard statement “Why would I train my competition?” HR sometimes views training as a double loss as that individual is more valuable, and will leave.
If you notice, this is the same arguments made in 1857.
