3. Should you share?

For social media managers, it’s important to stay up to date on cultural pulses to avoid posting in a way that may seem out of touch, controversial, or be insensitive - whether intentionally or unintentionally. 

Of course there’s no pleasing everyone. But as the world becomes more “woke,” there are certain lines that you want to be very careful about crossing. 

Now, if you do get in some hot water (it happens!) and you need to address your followers online swiftly and effectively, check out our Ultimate Guide for Crisis Communications.

We’re not here to tell you what to post or not post, however we do recommend using caution for the following national days:

National Days to Think Twice About Before Promoting on Social Media

  • January 26th. Australia Day 
    Why think twice? Many Australians are calling to #ChangeTheDate of this holiday and use the hashtags #InvasionDay and #SurvivalDay
  • February 8th. National Boy Scout Day
    Why think twice? The Boy Scouts continue to receive negative press over allegations of sexual abuse. 
  • November 11th. Columbus Day
    Why think twice? This holiday is now also commonly referred to as Indigenous Peoples Day to pay due respect and homage to the native people who already occupied the lands that Columbus claimed.
  • November 19th. International Men's Day
    Why think twice? Though created with the intention of promoting men's health, the day has received quite a bit of backlash. We recommend you proceed carefully when / if promoting.

And that's a wrap! What national days are you most excited to promote this year?
