Undelete Employee and Set Active Status

This trigger ensures that when an Employee record is undeleted, the “Active” field is automatically set to “True,” restoring the record’s operational status.

Solution:

trigger EmployeeTrigger on Employee__c (After undelete)
             { if(Trigger.isUnDelete){ if(Trigger.isAfter){
                                                                                EmployeeTriggerHandler.unDeletionofEmp(Trigger.New);
                           }
           }
}
public class EmployeeTriggerHandler{

     public static void unDeletionofEmp(List empList){
                    List<Employee_c> empListToBeUpdated = new
                    Lis<Employee_c>t(); for(Employee__c emp :
   empList){ Employee__c e = new Employee__c(); e.Id = emp.Id;
                  e.Active__c = true;
                  empListToBeUpdated.add(e);
}
 if(!empListToBeUpdated.isEmpty()){ update
               empListToBeUpdated;
         }
   }
}
