• Maintain HR process documentation, job aids, employee communications, and internal knowledge resources, using approved content and templates, while supporting future HR intranet development and content management.
• Process employment verifications, reference requests, unemployment claims, employee correspondence, maintain departmental calendars, and provide administrative support for HR operations.
• Support HR initiatives and special projects, including HRIS or ATS implementations, acquisition integrations, process improvements, employee programs, and other operational initiatives.

GREAT TO HAVE

• High school diploma required; Associate's or Bachelor's degree in Human Resources, Business Administration, or a related field preferred.
