-unethical to contact people living in North America when you know the breakdown is less than minimum wage in NA states and provinces
-unethical to gaslight workers saying YOUR low pay is due to their slow work ethic. Writing does take time. It's a skill, just like your management or HR job. Take responsibility where you need to please.
-claims that you make more after time are unethical. If you get any min wage job, do they tell you to start at a couple dollars per hour and hopefully, make your way up to min wage. No. Why? Because it's illegal. Also consider that min wage jobs (where you make more than here) require significantly less skill.
