Work Life Balance, the Anti-Stress tactic
I think a lot of folks forget that often due to the nature of IT, especially on the operations side, it's hard to take time off since they need to be available incase a server or application needs support, and so that normal workplace stress compounds all that much faster. Security teams often have to respond to incidents late at night or early morning, so sadly, while the nature of the role won't change, there is some potential to keep workers happy by offering better work/life balance. I also find often that as employees get older, start families, they often rethink more senior roles in order to keep that balance, as they don't want to forfeit the flexibility of working regular hours, or even remote at times.
As more millenials come into the workplace, more flexible job types emerge, especially with teams and even contract roles, we will see more emphasis on "work hard" but an even more increased pushback on making sure that IT folks are not only engaged in projects that bring them fulfillment in order to offset workplace stress, but also more flexible work models.
