Despite there being a great deal of research into this argument,
some authors do not agree with the interest of the scientific literature
in this relationship. One of them is Maslach (2011), who criticizes the
choice to investigate the relationship between work engagement and
physical health because the latter is determined by much more than
the work. In line with this position, in their longitudinal study, Britt,
Castro, and Adler (2005) found that engagement predicted higher
well-being and fewer physical symptoms when also controlling for
initial levels of well-being and symptoms. Other researchers have
shown that engaged employees seem to enjoy better mental and
psychosomatic health (see Schaufeli & Salanova, 2008). A positive
relationship between work engagement and health was found also
among teachers. The study of Hakanen et al. (2006) has indeed found
that work engagement was positively related to self-rated health and
workability among Finnish teachers.
