A traditional war is where two or more countries are fighting each other directly, like WWI or WW2. Traditional wars are (as they sound) traditional. These are how most wars were fought throughout history. A proxy war is where a war is instigated by one or more major powers but the major power itself does not actually get involved.
A good example would be the Cold War. The Cold War had many proxy wars within it; for example the Vietnam war. In the Vietnam war, the North was communist and the south was not. The Russians (USSR) was supplying North Vietnam and the Viet Cong (VC) with training and weaponry such as guns, tanks, planes, etc. But Russia (The USSR) never actually fought in the war itself, while America and their plan to contain communism, went and fought directly in Vietnam.
I believe it is workers had more negotiating power when standing together as a group rather than they had individually," since it would be very detrimental to a company if their entire workforce quit at once.
it depends on the era. now ide say its pretty nice. in the 1700 ide say it was brutal in the 1800 ide say yellow fever sucks (if i got that time right)
