Some award ideas to recognize an employees long service include gift cards or vouchers, electrical goods and extra vacation time or sabbaticals. Other ideas that are less common than they used to be are employer's memorabilia and watches or clocks.
Vouchers work well, as they can be given in various forms, and can be loaded with a monetary value to reflect an employees length of service. This reward also allows the employee to chose how to use the money. In terms of physical gifts, electrical goods have become more common with the emergence of iPads, 3D televisions and high-tech phones.
Many employers offer extra vacation time for ten, twenty or thirty years of service as examples. Some organizations offer a six week paid career break, the equivalent in pay or a mix of both.
