People who work some evenings and weekends are LEAST likely to resign.

Because they care.

The people most likely to resign work either:

• No evenings/weekends (disengaged) or

• Most (burn-out)

There's a crucial lesson here for managers: you shouldn't outlaw evening and weekend work.

In the ZIRP era, the employer friendly policy was to never work off-hours. But doing that actually encourages folks NOT to care.
