Besides coffee, custom service pins are one of the best forms of motivation for employees.
One of the things that boost morale is the recognition of a job well done. Custom lapel pins with gemstones indicating years of service go a long way towards providing this for great and loyal employees. Custom lapel pins would be consistent in color and logo design, but a different type of gem stone could indicated 5, 10, 15, 20 and 25 years of service.
Encouraging employees to wear them while on the job is also a wonderful way to display company branding and uniformity. Its also a great way to show others how appreciated the work force is.
