Seriously, they have boiler plate layoff templates, so you don’t need HR for layoffs.
They have automated processes that scrub resume’s, so you don’t need HR for that.
They have HR chatbots to answer basic questions, so you don’t need HR for that.
Beyond the chatbot, HR rarely answers any questions, so trim them.
We are FTE HR heavy because it looks good, just trim them back some. You can always outsource your HR needs if there’s a reason to have more of them. When you are finished with them, let the outsourced HR go. You can recoup the FTE HR pay back into the company.
