That’s a really thoughtful question Marce. Realistically it does but engineering companies are working hard to reduce this by increasing flexible working patterns that allow engineers to be with their family more.
As the others have said there is a lot of variety in the work expectations of engineers.
One reason that I chose to go in to the wind industry is that there is a lot of it going on in the UK so I can always spend weekends at home. In reality I can go several months without needing to travel and I have some choice about when I go away.
Many engineers really enjoy the experience of visiting new places and working on big projects & sometimes your employer will pay for your family to move to a new country with you so that you can do a specific job for a few years.
