That’s no Bogus it’s true.
So from my view at these times it was absolutely necessary to quit my position. The reason for
doing that was my son, named Maximilian and my daughter were studying at these time far away
from my home and from my wife and me and too much travelling for us/me at these times.
Layne paid my company for travelling, basics and car. My company invested time and man power
for transferring know how in different studies, opportunities in the market and teaching some
former Engineer Colleagues.
