I was brought up to go to school or work unless you were really physically unable to. I did the same with my DC. I'm sure until recently that was the normal expectation. It was certain yrhe case in the industry I worked in for the first 25 years of my working life.
DS has a low level management role in a service industry and is very frustrated by the ease with which colleagues are prepared to take a day off.
Has there been a real step change or is it my/his upbringing that was weird?
