$("#EMPLOYEE_ALT option:[value='"+$("#EMPLOYEE_ID").val()+"']").remove();

the above code gives the following error:

Uncaught Error: Syntax error, unrecognized expression: #EMPLOYEE_ALT\ option:[value='9999']

9999 is employee id witch is correct and this value suppose to be sent via ajax and return with something.

$.post("url", { emp: $("#EMPLOYEE_ID").val(),ajax: "yes"  },

    You have unexpected : in your selector. The correct selector would be

    $("#EMPLOYEE_ALT option[value='"+$("#EMPLOYEE_ID").val()+"']").remove();

    Try this:

    "#EMPLOYEE_ALT option[value='"+$("#EMPLOYEE_ID").val()+"']"

    The attribute selector doesn't haves : on it. That is used for CSS's pseudo-classes only.

    $("#remove").on("click", function() {
        $("#EMPLOYEE_ALT option[value='9999']").remove();
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
    <select id="EMPLOYEE_ALT">
      <option value="1">1</option>
      <option value="9999">9999</option>
    <button id="remove">Remove item '9999'</button>
