Hi Team
I have one object called Staff contract which linked with one another object called Staff. There is one apex class which restrcit all staff contracts from normal user except admin. Logic is..
if UserID!=OwnerID then no one can see other's staff contracts.
Now problem is, in staff contract objects, there are 2 record types, one is Staff and another one is Field staff. I want to open all field staff contracts for each and every profile.
My question is how to restrict staff contracts in respect of record type. I am attaching the entire class, it will be helpful if anyone can modify the class as per my criteria.

Here is the class...
// Comments:    [Controller for Insert Staff Contract Sharing records.]
Public Class ctrlAddStaffContractSharing{
        
    //List for Staff Contract sharing records.
    List<Staff_Contract__Share> lstStaffContShares = new List<Staff_Contract__Share>();
    
    //List of Staff Contract records.
    List<Staff_Contract__c> lstStaffCont = new List<Staff_Contract__c>();   
     
    //lstGroup will enclose user record which has name ED and HR Head.

        //Delete existing sharing records of Performance Evaluations
        List<Staff_Contract__Share> lstStaffContShareRemove = [SELECT ID,ParentId,RowCause

             //Sharing with Staff Owner
            setShareTo.Add(mapStaff.get(objStaffCont.Staff__c));

            }
        }
    
        //Insert all of the newly created Share records and capture save result
