Generally restrictions are against working for a local company, since that would be a workaround of getting the right visa for you.

I think most tourist entries are ok with working for a company abroad, especially if some jobs might require to step-in while on vacation.

There should be footnotes in forms that tourist visa works for business trips. It's often ok in that sense, not as in throwing in the straw hat and Hawaiian shirt to trash can just past the border control is ok or not

I'd rather ignore it since tourist visas are short. The alternative is to add rules to stress some people out, and have others willingly ignore them as it gets you into the idiotic space of having a rule that's not really enforced or worse, not even enforceable in a reasonable way.
