The USPS Ethics Office has created a 2021 Holiday Ethics Guide to help employees comply with the rules about giving and receiving gifts.
The guide also details the rules about holiday office parties:
• Food and refreshments may be shared in the office with co-workers at all levels. Participation must be voluntary and contributions of money ($10 or less), food or other items also must be voluntary.
• Office parties can be held at a restaurant or an outside caterer can be brought in, requiring a per-person charge for those attending. Employees who do not wish to participate cannot be required to contribute.
Additionally, the document offers guidance on perishable gifts.
Employees who receive a perishable gift that is valued at more than $20 from a customer or supplier have three options: The employee can donate it, share it or destroy it.
A perishable gift is an item that would perish in the process of returning it to a sender. Examples include fresh cut flowers and fruit, but not chocolate.
