Work from anywhere in the world policy

Bore da o Gymru / Good morning from Wales,

I work for a small, environmental NGO and we’re considering a ‘work from anywhere in the world policy.’ This could be for up to 1 or 3 months of the year. I haven’t found anything in the resources section and I’m struggling to find examples online. Does anyone have anything they could share or signpost me to? Diolch / Thanks!
