Two of our employees—a married couple—for years have requested extra unpaid time off for vacations. The husband works for me, the wife works for the company owner. We recently notified all employees that we would no longer grant any additional time off. I’ve made it clear to the husband that he won’t get any additional time off. The owner, on the other hand, sees no problem with giving both of them unpaid leave this year, even while other employees have to live with the new rule. How should I handle this?—J.L., Wisc.
