I love how quickly people respond to their e-mail.
Valerie Schumacher of SFS sent me to Human Resources. There, Sheli Galipo forwarded my inquiry to staffing specialist Serena Harris. Valerie suspected that Margi was thinking of the policy that "graduated seniors cannot be hired to continue at a student job during the summer" and the final word from Serena is:
Graduated seniors cannot be hired to continue at a student job during the summer unless it is approved by the Controller of the college. There is no such policy barring just graduated seniors for applying for regular Smith jobs.
