jQuery issue on IE

Hello Techies,
I wrote the below code to fetch current user and manager name - it works well on Chrome but on IE it doesn't work on page load for first time. But when I refresh the page it works. Anybody came across this issue.

$(document).ready(function () {

    SP.SOD.executeFunc('sp.js', null, function () {
        retrieveUserInfo();
    })

});


function retrieveUserInfo() {

    $("nobr:contains('Claim ID')").parent('h3').parent('td').parent('tr').hide();
    var currentuserName = $().SPServices.SPGetCurrentUser({
        fieldName: "Title"
    });

    var managerName;
    $().SPServices({

                        operation: "GetUserProfileByName",
                        async: false,
                        AccountName: $().SPServices.SPGetCurrentUser(),
                        completefunc: function (xData, Status) {
                                                $(xData.responseXML).find("PropertyData > Name:contains('Manager')").each(function () {
                                                managerName = $(this).parent().find("Values").text();
                                                                                                                                       });
                                                                }

    });


    var PickerTitle = "Employee";//Employee is Column name

    $('input[title="' + PickerTitle + '"]').val(currentuserName).attr('size', 40);
    $('div[title="' + PickerTitle + '"] span.ms-helperText').hide();

    // Select the target user field from the dictionary of user fields on the page.
    var peoplePicker = SPClientPeoplePicker.SPClientPeoplePickerDict[$('[title="' + PickerTitle + '"]')[0].id];

    // Resolve the user using the value set in the input field.
    peoplePicker.AddUnresolvedUserFromEditor(true);

    var mgrName = "Employee Manager"; //Employee Manager is column Name
    $('input[title="' + mgrName + '"]').val(managerName).attr('size', 40);
    $('div[title="' + mgrName + '"] span.ms-helperText').hide();
    var peoplePicker1 = SPClientPeoplePicker.SPClientPeoplePickerDict[$('[title="' + mgrName + '"]')[0].id];
    peoplePicker1.AddUnresolvedUserFromEditor(true);

    SPUtility.GetSPField('Employee').MakeReadOnly();// To make the columns as read-only
    SPUtility.GetSPField('Employee Manager').MakeReadOnly();// To make the columns as read-only

}
