On Wednesday, participants in a national strike, dubbed “A Day Without A Woman,” didn’t go to work. But many women did — and they shared their reasons for doing so on social media.

The strike was a project by the organizers of the Women’s March on Washington, which took place Jan. 21, the day after President Donald Trump’s inauguration. Similar marches took place that day across the country.

Participants in the strike, which coincides with International Women’s Day, were encouraged to avoid both paid and unpaid work, avoid spending money — except at women and minority-owned businesses — and to wear red.

But some women countered the protest by going to work. They shared their reasons for doing so with the hashtag #WeShowUp:

Some men used the hashtag to thank the women in their lives for their hard work.
