For nannies and housekeepers: A bonus of a week’s pay is standard for domestic help who’ve been on the job a year. Give very recent hires a day’s pay for every month spent on the job, and for five-year veterans, bump the week’s pay to two. Babysitters who work once a week or more should get a night or two of extra pay.
For garbagemen: $20 in cash makes “a nice tip for a garbageman.”
For doormen: Figure $50 to $150, and lean to the high side if your doorman provides such extra services as calling for cars or carrying laundry.
For delivery people: If you receive packages once a week or more from the same USPS, FedEx, or UPS delivery person, hand them a holiday card with cash or a gift card inside. “A typical amount is anywhere from $20 to $50.”
