Inside Report (6)

Go ahead and roll up your sleeves. All that extra work you do may not be as exhausting as you think.

The latest word from Canadian researchers on the effects of moonlighting and overtime suggest that they have little or no impact on regular job performance.

Two professors of management at Montreal's Concordia University, surveying workers at six Canadian companies, found those who put in extra hours on the job or moonlight tend to belong to more voluntary organizations, attend more meetings, and hold more offices than 9 to 5 workers.

Implication for managers: banning moonlighting or requiring rigid reporting systems may not be as necessary as many companies have assumed.
