DESCRIPTION:
As an Administrative Assistant II supporting our Detroit and Miami sites, you will help colleagues and site leaders get the details right—from contract-based union pay and benefits administration to welcoming, well-run site events. You will be a reliable point of coordination for employees, union representatives, Human Resources, Payroll, benefit providers, and site leaders. Your follow-through will help resolve administrative issues clearly and on time, while your communication and event-planning skills will help create a connected site community.

What you will do

Union payroll and benefits administration

• Administer and coordinate union-related payroll and benefit transactions in line with applicable collective bargaining agreements, established procedures, and payroll deadlines.
• Process union vacation pay and entitlement requirements, overtime and premium pay items, contractual payroll additions, and supporting documentation; verify information and flag discrepancies for resolution.
• Prepare and submit union pension reports and related benefit documentation, and coordinate retiree life insurance payments and records.
• Maintain a clear, organized log of payroll, insurance, pension, and benefit questions. Confirm the issue and supporting facts, route it to the appropriate Payroll, HR, benefits, pension, or provider contact, track it through resolution, and communicate status and outcome to the employee.
• Track and administer union members’ time-off allocations—including PTO, sick time, and personal days—in accordance with applicable collective bargaining agreements and established procedures. Maintain accurate balances and records, coordinate required Payroll or HR updates, and follow up on discrepancies. Protect sensitive employee and compensation information, and support timely onboarding.

Site events, engagement, and budget coordination

• Own the site events calendar and coordinate the planning and delivery of celebrations, recognition activities, engagement events, town halls, and other colleague gatherings across Detroit and Miami.
• Invite ideas and participation, build positive conversation about what colleagues would enjoy, and turn suggestions into practical plans that fit the audience, schedule, site requirements, and available budget.
• Coordinate event details such as venue or space, vendors, catering, supplies, invitations, communications, accessibility, setup, and day-of logistics; confirm owners and follow up on commitments.
• Manage the approved site activities budget: maintain a current view of commitments and remaining funds, obtain required approvals, coordinate purchasing, reconcile expenses, and raise cost or timing concerns early.
• Work with Site Leadership, HR, Business Resource Groups, and colleague volunteers to make activities inclusive, well communicated, and smoothly executed.

Site and leadership support

• Provide organized administrative support to Site Leadership, including meeting coordination, agendas, notes, action tracking, presentations, reports, spreadsheets, and correspondence.
• Coordinate quarterly site newsletters and support clear, timely communication about events and site activities.
• Support Workday or similar HR system transactions, new-hire documentation, orientation coordination, office supplies, purchasing, audits, and administrative record reconciliation.
• Identify opportunities to simplify, standardize, digitize, or automate routine administrative work, and support cross-functional projects as assigned.

How you will succeed

• You are accurate and discreet with pay, benefits, and personal information, and you understand the importance of deadlines and reliable records.
• You bring a methodical approach to resolving issues: gather the facts, identify the right owner, keep the employee informed, follow through, and document closure.
• You are personable and approachable. You communicate comfortably with colleagues at all levels, union representatives, leaders, vendors, and service providers, adapting your style to the audience.
