United News:
This week, we are pleased to host members of FNBSM’s leadership team at our annual Senior Leadership Conference in Greenville, SC. Two-hundred leaders from across the footprint will gather to hear from executives and guest speakers, learn more about our company, and meet teammates. This year’s theme is “Be the Heart,” and will focus on the heart of leadership.

Human Resources:
United and FNBSM leaders continue to meet to complete the job mapping process. While many of the job titles will remain the same, if an employee’s job title changes, HR will notify those employees in writing. The communication will explain that while a job title might change, the functions of the job will remain the same. United will honor FNBSM’s original hire dates, which determine eligibility for certain benefits including vacation and anniversary milestones.

United’s HR Department will be covering a topic each week to answer questions ahead of the transition, including:
• Compensation specifics
• 401K retirement and deferred compensation
• Benefits overview
• Payroll

We welcome any questions you might have through our unique HR inbox set up for FNBSM employees:
