Deciding Which Holidays to Observe

With so many diversity and inclusion events and religious observances, it can be a challenge to determine which to observe. When building your DEI calendar for the year, be sure to ask your employees what holidays would mean the most to them.

You can do this by leveraging your ERGs, building a task force, or sending out a quick pulse survey. The important thing is to listen carefully to your team and take their thoughts into consideration.

Example Programming for DEI Holidays

So how do you bring diversity, equity, and inclusion into your engagement programming? Cooleaf offers DEI programming to help you foster a more inclusive culture, along with a digital platform to build a sense of belonging and encourage employees to grow deeper connections. Here's a few examples of DEI holiday programming hat has helped our customers spark conversations on their teams.

May - Cinco De Mayo

Cinco de Mayo is widely celebrated in the U.S., but the holiday’s origins are often misunderstood.

In Mexico, Cinco de Mayo is a celebration of the first battle of Puebla, when the Mexican Army successfully defended the city against invading French forces in 1862. In fact, many U.S. citizens make the common mistake of identifying Cinco de Mayo as the Mexican Independence Day, which is in September.

To celebrate this holiday, we encouraged employees to learn more about the real history of Cinco de Mayo. By sharing resources and guiding employees to start having conversations, you can strengthen the culture intelligence of your team.

July - Nelson Mandela International Day

Nelson Mandela International Day celebrates the legacy of the former President of South Africa and anti-apartheid revolutionary, who shined an immense light on the world. Celebrated annually on his birthday July 18, Nelson Mandela International Day is a global call to action that celebrates the belief that every individual is capable of transforming the world.

For this holiday, we challenged employees to consider their beliefs around making an impact. In the example below, employees used the Cooleaf platform to connect with one another and share how they define a commitment to social purpose.

Encourage positive impact through creative social responsibility challenges

Additionally, simply taking the time to share information and resources about diverse national events in your communication channel of choice (such as Slack or Microsoft Teams) can be a great way to start a conversation and bring DEI into daily work life!
