This document discusses the bright and dark sides of work. It notes that work engagement, characterized by vigor and dedication, represents the bright side. However, rising work intensity without increased job control can lead to greater psycho-social risks and health dangers on the dark side. While work engagement is increasing, possibly due to greater skills and job interests, this rise is accompanied by higher job-related anxiety, especially in higher skilled occupations. Overall trends regarding job quality across Europe are worrying as work intensity rises without consistent increases in skills discretion and other positive job characteristics.
