Three-component commitment and turnover: An examination of temporal aspects

SEM (N = 182) was employed to examine implied temporal aspects of three-component commitment theory as they relate to turnover. Consistent with expectations, affective commitment predicted subsequent turnover in an immediate and relatively short interval of 4 months, but failed to do in a much longer but outlying interval of 5–12 months. Side bet commitment failed to predict turnover in the short, immediate interval, but did so robustly over the longer albeit more distant interval. Normative commitment predicted turnover in neither the near term nor outmonths. Turnover rates for employees with low affective commitment were much higher than those with high affective commitment in the first quarter of a 1-year monitoring period, but subsequent turnover rates were roughly the same for the two groups. In contrast, turnover for employees with low side bet commitment was only slightly higher than the high side bet group in the first quarter, but over the remainder of the year cumulative turnover for the low side bet group exceeded that for the high side bet group by increasingly large margins. These results are consistent with theory suggesting that decrements in affective commitment (1) often occur suddenly and just prior to employees' leaving and (2) reflect general disaffection and an impetus to leave that is already exists at the point of attitude measurement. Results comport with theory describing side bet commitment as (1) an appraisal of leaving costs that, in the aggregate, are unlikely to change suddenly and (2) a relatively stable attitude that serves primarily to prevent turnover should some independent motivation to leave arise.

Research highlights
► Immediacy of turnover measurement intervals was pitted against interval length to compare commitment types temporally.
► Affective commitment robustly predicted subsequent turnover in an immediate and relatively short interval of four months.
► Affective commitment failed to predict turnover in a much longer but outlying interval of five-twelve months after attitude measurement.
► Side bet commitment side bet commitment failed to predict turnover in a short immediate interval of four months.
► Side bet commitment predicted turnover robustly over the longer, albeit more distant, interval of five-twelve months.
