Disable all users in a specific OU

Disable all users in a specific OU

I'd like to automate some procedures with all users into a specific OU.
When a employee is fired, we have to do (in ADManager):

1) We disable the user.
2) We move a user to a OU called "Disabled Users".
3) Remove all groups the user is member of.

I think a specific automation:
The techician manually moves the user to the OU "Disabled Users".
The Automation runs disabling the user and removing all groups.

Anyone can help me with this.

(Sorry my english).
