Management wants to hire a clearly incompetent employee. What to do?

Question

Personnel Management

There is a project on cs-car multi-vendor, the management wants to hire a certain person "administrator", who should perform the functions of a content manager and at the same time have access to the code. As I understand it, this employee will then allegedly make changes in the system itself, I perfectly understand the delusional nature of this idea, because there are 2 specializations - a content manager and a developer, but so far there have been no reactions to my letters with arguments against.
Perhaps someone has experienced similar problems when management wants to close two positions for a small amount, trying to hire a similar employee. What are the arguments against such a decision? My statements that I will not give access to such a person while I work here, they again ignore.
PS One of the leaders believes that he understands web development and claims that there is no difference between conditional wordpress and cs-cart multi-vendor, and even a junior can do a great job (in the context of a developer job) without having experience with this CMS .

Answer 1

It happens everywhere. That is the essence of business. It's just that somewhere the situation is tolerable, somewhere it contradicts the technical meaning.
You decide what to do. In a crisis, you can always find a person who is simply ready to work for money, and if they also give you the code to tinker with, then you can get development - it depends on employment.

my statements that I will not give access to such a person while I work here, they again ignore it like that.

Put the site on git, implement the review code and give access.
In the case of sides, you can always provide a report on what and how was done wrong and roll back the changes. Take responsibility off yourself.
Well, either change jobs, let them rake themselves.

Answer 2

If he has access only to the admin panel, let him pick. The main thing is not to climb into the source code of the template. As far as I remember, it can be easily broken from the admin panel.
Remove responsibility from yourself.
