December 2025 DEI Observances

Written By The CultureAlly Team

December is a month of many holidays and celebrations, both religious and secular. Bright twinkly lights, cozy meals with family and friends and gift exchanges often bring hope and joy to many during this time of year.

Whatever the reason for celebration, it’s important to keep in mind that not everyone observes the same holidays.

How to Celebrate December DEI Observances in the Workplace

Be inclusive

Christmas can take center stage when it comes to celebrations in December. Rather than wishing your co-workers “Merry Christmas”, opt for “Happy holidays”. Have a Holiday party rather than a Christmas party that incorporates traditions from a multitude of celebrations. Encourage employees to share aspects of the cultural or religious holidays that they observe. And make sure that holiday parties are optional, so that those who do not celebrate do not feel penalized for not attending. 

Be mindful

Be mindful when scheduling events in December to refrain from conflicts with different celebrations. In North America, it is standard for employees to receive time off for Christmas and it’s surrounding days even though many employees may not be Christian or celebrate the holiday. Acknowledge that employees might be observing other holidays than yourself. 

Be knowledgeable

Find out which holidays your employees celebrate in December.This could affect what time off your employees require, for observing religious holidays and can be useful when planning holiday events. You might want to send a card, e-mail or simply state your well wishes for the variety of celebrations your employees are observing in December. 

Let the December festivities begin

While December can be a month of fun and festivities, it is important that everyone in the workplace feels included. For some, religious or cultural holidays can be an important part of their faith and values. Make sure workplace holiday events incorporate aspects of a variety of December holidays. Spread awareness about different December holidays by acknowledging what your employees are observing. Learning about each other’s beliefs and getting to know one another is beneficial for all and improves engagement and collaboration.
