The advantage of this revised definition is that it (a)
maintains the distinction that has empirically been shown to exist
between task performance and OCBs (MacKenzie, Podsakoff, &
Fetter, 1991; Motowidlo & Van Scotter, 1994; Rotundo & Sackett,
2002), (b) is more consistent with Borman and Motowidlo’s
(1993) definition of contextual performance, and (c) avoids some
of the difficulty with viewing OCBs as discretionary behavior for
which an individual might not receive formal rewards.
