I, too, am familiar with this scenario. Unfortunately, I have firsthand experience with the devastating effects of depression. Dickens' poignant descriptions of the condition and its impact on a person's sense of self are hauntingly accurate.
I also agree with Iam that many individuals have witnessed colleagues repeatedly taking time off due to mental health issues. However, it's essential to acknowledge Doodledog's crucial point: the actual cause of this problem lay, and often lies in underlying workplace issues, in this case understaffing. This, rather than the individuals themselves, is often the root cause of the pressure and stress placed on colleagues.
It's essential to distinguish between those who are mentally ill and the often-inadequate workplace systems that can exacerbate their conditions. While individuals who become mentally ill are not responsible for poor workplace systems, it's clear that systemic problems, such as understaffing, can play a significant role in the development of mental health issues.
I'm not sure that in this case the underlying problem was understaffing. That certainly contributed to making my experience of my colleague's absence unbearable, but the underlying systemic problem was more as Calendargirl suggests - that she was employed to do something for which she was temperamentally unsuitable, and her response to that was to put her own comfort first and stay at home, rather than to accept that she might be better off in a different role. She openly stated that she'd be happier doing something else, but that she didn't want to take a cut in salary. Understaffing meant that her work fell to me, but wasn't responsible for her attitude.
IMO, that attitude starts young. If a child learns that being ill means lying on the sofa with the TV on and snacks on demand instead of double maths or a cross-country run, and then that dropping out of a friend's teaparty when an invitation to something more interesting comes along, and later that they can get qualifications despite opting out of the bits they don't like, then why are they suddenly going to start considering the impact on other people?
I repeat - none of that is to suggest that mental illness is not real, or that those who suffer from it are malingering. I don't believe that at all. I am agreeing with TB (and others) that despite the fact that people do suffer from mental illness there are also those who see discomfort as illness and pass the buck to others.
I don't know how else I can say that, so this will be my last post on this thread.
