YES!!!!!!!!
PI's are the hardest working and moral people I ever met. (And some of the most beautiful women *wink*)
I have worked with literally hundreds. They run the spectrum just like everyone else:, hard working, lazy, dumb, smart, you name it. There are traits in my profession they have a problems with: insisting on speaking their language when together, in front of non Tagalog speaking staff and patients; upon becoming supervisors, promoting their own over better qualified non Filipinos; and maintaining the professional boundaries between patients and staff.
