Please try below code 
trigger EmployeeMaster  on SP_Master__c ( after insert, after update )
{
    Set<id> EmployeeRecords = new Set<ID>();
     
    for(SP_Master__c sp : trigger.new)
    {
        if( sp.Active__c == true && sp.License_Type__c == 'LI')
        {
            EmployeeRecords.add(sp.Employee_Code__c);
        }
    }
     
    Map< Id ,Employee_Master__c> EmpMaster = new Map< Id ,Employee_Master__c> ( [select id,Name,SP__c,LI_License_No__c from Employee_Master__c where id IN :EmployeeRecords and SP__c = false ] ) ;
 
    List<Employee_Master__c> lstEmpMasterToUpdate = new List<Employee_Master__c>();
     
    for(SP_Master__c sp : trigger.new)
    {
        if( sp.Active__c == true && sp.License_Type__c == 'LI')
        {
            if(EmpMaster.containsKey(sp.Employee_Code__c))
            {
				Employee_Master__c empMaster1 = EmpMaster.get(sp.Employee_Code__c); 
                empMaster1.LI_License_No__c=sp.License_Number__c;
                empMaster1.SP__c=True;
                lstEmpMasterToUpdate.add(empMaster1);
            }
        }
    }
    if(lstEmpMasterToUpdate.size() > 0 )
    {
        update lstEmpMasterToUpdate;
    }
}

in above code you forget to add below line
lstEmpMasterToUpdate.add(empMaster1);

Hi Supriyo,

Try this...
 
list<Employee_Master__c> EmpMaster = [select id,Name,SP__c,LI_License_No__c from Employee_Master__c where id IN :EmployeeRecords and SP__c = false ];
    if(EmpMaster.size()>0)
{
for(SP_Master__c sp : trigger.new){
    for( Employee_Master__c empM : EmpMaster )              
    {
        empM.SP__c = true;
        empM.LI_License_No__c=sp.License_Number__c;
        EmpMaster.add(empM);
    }
 }
}
    if(EmpMaster.size()>0)
    {
        update EmpMaster;
    }
}

I have tried your code as below.

trigger EmployeeMaster  on SP_Master__c (after insert,after update) 
{
    
    Set<id> EmployeeRecords  = new Set<ID>();
    
    for(SP_Master__c sp : trigger.new)
    {
        if( sp.Active__c == true && sp.License_Type__c == 'LI')
        {
            EmployeeRecords.add(sp.Employee_Code__c);
        }
    }
    
    list<Employee_Master__c> EmpMaster = [select id,Name,SP__c,LI_License_No__c from Employee_Master__c where id IN :EmployeeRecords and SP__c = false ];
    if(EmpMaster.size()>0)
{
for(SP_Master__c sp : trigger.new){
    for( Employee_Master__c empM : EmpMaster )              
    {
        empM.SP__c = true;
        empM.LI_License_No__c=sp.License_Number__c;
        EmpMaster.add(empM);
    }
 }
}
    if(EmpMaster.size()>0)
    {
        update EmpMaster;
    }
}

after that when I am trying to edit my SP Master record and save it is showing me 

Error: Invalid Data. 
Review all error messages below to correct your data.
Apex trigger EmployeeMaster caused an unexpected exception, contact your administrator: EmployeeMaster: execution of AfterUpdate caused by: System.FinalException: Cannot modify a collection while it is being iterated.: Trigger.EmployeeMaster: line 18, column 1

Please help.
