GPO for local administrators (not restricted groups)

[nave 0]

hello folks, 

I worked in A small company , we have like 100 employees that all are under A group that called "all_employees" , I need to find A way to insert every employee domain user to his local administrator group on his own laptop.

so I've been thinking about A GPO that can insert the group "all_employees" to the local "administrators" group on every laptop but the problem I come across (when I presented the idea to my team leader) is that every employee will have A full administrative rights to all the computers in the company. 

I need to have A way that every employee is just an administrator on his own local machine.
