Son unit is part of that as he’s employed by a automobile manufacturer or OEM and not a 1st tier or lower automotive parts supplier.
The differences between these two strata can be illustrated by this.
In preparation for a new model launch, son unit and others have been told that for the remainder of this year, they can expect to work weekends as well as a full weekday schedule. Mentioned this to someone else who told me during his time at a parts supplier for this OEM, employees had to work 7 days a week for 8 months to keep up with the OEM’s demand for parts.
Insane, no? But that is an example of how life can be for a OEM parts supplier
