I wonder if this advice is informed by the author's experience in the UK. In the Northern California software/tech industry, 2 weeks notice is the standard courtesy. It's also, I've found, widely accepted that having someone who doesn't want to be there can be corrosive to team dynamics so both employer and employee have an interest in aiming for the minimum time needed for an orderly hand-off. That tends to be two weeks or less.
