Counting Multiple Occurance Sql

Declare @MYTable Table
(
RecordID int identity,
EmployeeID int,
JobCode varchar(4)
)
Insert into @MYTable Values(1,'123')
Insert into @MYTable Values(2,'123')
Insert into @MYTAble Values (1,'123')
Insert into @MyTable Values (2, '123')
Insert into @MyTable Values (3,'123')
Insert into @MYTable Values (1,'222')
Insert into @MYtable Values (3,'222')
Insert into @MYTable Values (1,'222')
Insert into @MyTable Values (4,'222')
Insert into @MyTable Values (5,'123')
Insert into @MyTable Values (6,'123')
Insert into @MyTable Values (7,'457')

Select * from @Mytable

The each employee can come to this table multiple time however
the job code should be different for each every single record.
So If I have to check this error and see which record has been repeated with
the same Employee ID and JobCode and how many times. how would i do that
Thanks,
