Pro tip…if you are going to refer to something in a post of yours that wasn’t in the thread you are responding to, it’s helpful to link to it.
You just assumed I read that other post…which I hadn’t.
As to “President and CEO”….”roles” it appears that the plural has some meaning to you in this discussion.
It really shouldn’t as a lot of companies combine the titles of President and CEO, because almost all state law only legally requires a President, Treasurer and Secretary as “Corporate” officers. CEO, CFO, CHRO, COO etc. are essentially made up, but commonly used titles for a company. So when the Corporate documents show the President as so and so, and they happen to also have the title “CEO”…they are combined as “President and CEO”.
