Travel to Europe (Spain) while remote working from USA-based company [duplicate]

This question already has an answer here:

  • As a US Citizen, if I'm visiting the Schengen region, can I “work from home”? [duplicate] 1 answer
  • Do I need a visa to work remotely in Europe as a Canadian citizen for six weeks? 1 answer

This question mentions some of the laws and challenges and what have you of working remote from Europe to USA, So does this one, but how about the other way around? If I am working remotely in an USA-based company, living in the USA and I wish to travel to Europe for a short period of time (a month or less), would there be any current issues with Visas or the Visa Waiver Program? Or is it safe, providing enough proof that there’s no wish to stay?
