Summer is here, and for many working parents, that means frantically trying to juggle childcare with their jobs for weeks on end. For many, professional childcare providers are either unaffordable or inaccessible, which means caregivers are forced to take time off, work around their kids or find other solutions.

The juggle is real for Meg St-Esprit, a freelance journalist based in Pittsburgh, PA, who has four children aged between four and 11.

At the end of May, she updated her email signature to let professional contacts know that due to childcare constraints, her responses would be a little slower than usual over the summer months.

The signature read: “Please note I may be slower to respond to email in the months of June, July and August due to the United States’ inability to provide affordable childcare for working mothers.”

St-Esprit told Fortune she decided to use the signature—a screenshot of which went viral on social media—after receiving “a snippy email” from a client, who was unhappy that she hadn’t responded to a non-urgent email after around 18 hours.

“It was late, and I put it on my email signature—I just thought, I'm just going to be upfront about the fact that I have four kids,” St-Esprit told Fortune.

However, over the next couple of days, she questioned whether she should remove the new signature from the bottom of her email responses.

“I thought, maybe it's not very professional,” she said. “But then people I was emailing for work started responding to it —they were like, ‘I love this, I'm going to steal this, this is so great.’ It just struck a chord, I think, laying it out there and saying, listen, I'm not going to be on my game all summer.”
