The reference qualifier just needs to get your subset of users and return a query string that will exclude them from the query when the field is opened. Create a script include and name it excludeITUsers. When you tab out it should populate the script field with some code which is defining the class. Add the following code in the bit it tells you to:

//name your function
excludeITUsers: function(){

//create an array
var arr = [];

//glide into the user group table
var gr = new GlideRecord('sys_user_grmember');
gr.addQuery('group', 'sys_id of the IT group');
gr.query();

//add it users sys_id to the array
while(gr.next()){
arr.push(gr.getValue('user');
}
//return the query string to say sys id is not one of the it guys
return 'sys_idNOT IN' + arr;
}

Call it as per that link: 

javascript: new excludeITUsers().excludeITUsers()

ok so you've configured it as a classless script include so you will need to call it in the advanced reference qualifier as below:

javascript: excludeIT()
