To date the focus of the retirement research has been on identifying the factors that predict older workers' decision to retire from the workforce and the factors related to retirement adjustment and satisfaction. The factors associated with the decision of retired people to return to the labour force have received little attention (Griffin and Hesketh, 2008; Maestas, 2010). This is due, in part, to the fact that unretirement is a relatively recent phenomenon. Historically, when people retired from the workforce, they remained retired. However, in most developed countries, there has been a growing trend towards retired people returning to paid employment. For example, Maestas (2010) found that 26 percent of retired people in the US returned to the workforce. In Australia, Griffin and Hesketh (2008) found the incidence of unretirement to be 38 percent.

It is now recognized that retirement no longer means permanently leaving the workforce (Adler and Hilber, 2008). In fact, Brown et al.
