When someone mentions UPS, most people think of the well-known large brown trucks and employees clad in brown uniforms. However, there are plenty of other jobs at United Parcel Service. Office workers, managers, customer service representatives, Accountants, supervisors and various executives work for UPS. Many employees work for this company on a part-time basis. Since UPS handles a higher volume of parcels around the holiday season, some part-time jobs are restricted to the winter months. The majority of extra workers at that time are warehouse sorters, loaders or drivers. This international company has a highly organized system for tracking, sorting and delivering packages. Before they are able to work independently, new part-time employees receive specialized training and on-the-job practice. To qualify for part-time employment at UPS, applicants must meet the requirements for the desired position. For example, applicants who wish to become drivers must have their license and a clear DMV record. Warehouse workers must have a high school diploma or equivalent. Some jobs may require skill testing. In addition to these requirements, applicants must pass a drug test. A physical exam may also be required for some positions. One of the biggest advantages of working for UPS is the possibility for advancement. Since the company believes in promoting within the company, it is possible for loaders to promote to supervisors. After more training, supervisors may promote to higher administrative positions. In addition to this, employees who start as part-time workers may eventually promote to full-time positions.
