It isn't what you asked for, but a better solution is to have an
Employees table, A "roles" table, and a Employeesroles table.
So, one employee row for every person.
Roles would start with two rows, "Sales Rep" and "Telemarketing"
and Employeesroles would track the relationships of which people were
reps, and which were telemarketing, and which were both.
