Use New-Hire Employee Name Badges
If you lead an organization that uses employee ID badges, considering using a different color or a special designation on the badges for newly hired employees for at least their first 30 days and ideally up to 60 days.
Imagine how welcoming it will be for your new hires when employees recognize your newly hired employees' status via their special badges and then when your longer term employees introduce themselves to the new employees in halls, on elevators, in your break room, in the parking lot and at large group meetings.
Some people call this a "hello" culture. It's a culture that helps to quickly develop relationships. And, it's a culture that ensures your new hires feel welcome during their critical onboarding time period.
