Hi I have a vf page on a custom object and I can edit it and click on the save button and it looks like the changes have been made until I refresh the whole page and then my changes are no longer saved to my vf page block

Here is my code
 

<apex:page cache="false" standardController="Employee__c" tabStyle="Employee__c" showHeader="false" sidebar="false">
    <apex:form id="all" >
        <apex:pageMessages />
     
        <apex:pageBlock title="Worker Licence Record Section" mode="inlineEdit">
     
        
           <apex:pageBlock mode="maindetail">
           
           
           

           
            <apex:pageBlockButtons location="top">
                
             
                
                <button onclick="location.href='/apex/Worker_Section?id={!Employee__c.Id }'" id="saveButton">
                    Save
                </button>
                
                <button onclick="location.href='/apex/Worker_Section?id={!Employee__c.Id }'" id="cancelButton">
                    Cancel
                </button>
                
            </apex:pageBlockButtons>
            <style>
                     .bPageBlock {
                                background-color: white !important;
                     }
                     
                     .pbHeader{

        color:grey;

        width:100%;

        font-size:90%;

        }

               </style>
