“Workaholism involves a personal reluctance to disengage from work and a tendency to work or think about work anytime, anywhere (McMillan et al, 2003).” (p. 509)
“Workaholics typically have difficulty in switching off, think about work up to six more frequently after hours, talk about work more frequently, more achievement oriented, and more task-focused than non-workaholics (McMillan, 2002).” (p. 509)
“…time invested in work, while controlling the financial needs for this investment.” (Harpaz & Snir, 2003, p. 291)
“Workaholics place their work firmly in the centre of their lives and progressively all other aspects of their life, such as family, sport and other interests, are no longer the focus of attention. Workaholics feel the urge to create and respond to self-imposed demands…” (Buelens, 2002, p. 63)
