My US colleagues are constantly doing overtime and working weekends but this seems like a cultural thing (which they'd like to impose on us) rather a specific fear for their jobs (though that definitely exists). And the jobs keep flowing to us in Ireland regardless (i.e., US vacancies are generally filled in Ireland). In my experience, those extra hours haven't amounted to any great advantages for them but, then again, they are paid about 3x as much as we are.
