With Christmas just around the corner, McDonald's is making sure its underpaid employees don't forget to generously tip their stable of domestic servants.

On its employees-only "McResource Line" website, the fast-food behemoth posted a tipping etiquette guide that suggests holiday bonuses for such common hired helpers as au pairs (one week's pay or a gift from the family), housekeepers (one day's pay), and pool cleaners (the cost of one cleaning).

Don't worry: McDonald's didn't forget about its employees' dog walkers, massage therapists, and personal fitness trainers — they get a handsome tip too.

No word on what the guide suggests a corporate giant with more money than sense should give its struggling workers, but they're probably better off in any of the other mentioned professions.

CNBC reached out to McDonald's to ask what the fuck and were told the content was "provided by a third-party partner and quotes from one of the best-known etiquette gurus, Emily Post."

Spokeswoman Lisa McComb said McDonald's will "continue to review the resource and will ask the vendor to make changes as needed."

The McResource Line first made headlines last month when it offered employees some "helpful holiday tips" such as eat less, complain less, and sell your unwanted gifts for "quick cash."
