paragraph_text: One of the earliest sexual orientation classification schemes was proposed in the 1860s by Karl Heinrich Ulrichs in a series of pamphlets he published privately. The classification scheme, which was meant only to describe males, separated them into three basic categories: dionings, urnings and uranodionings. An urning can be further categorized by degree of effeminacy. These categories directly correspond with the categories of sexual orientation used today: heterosexual, homosexual, and bisexual.

paragraph_text: Full - time employment is employment in which a person works a minimum number of hours defined as such by his / her employer. Full - time employment often comes with benefits that are not typically offered to part - time, temporary, or flexible workers, such as annual leave, sickleave, and health insurance. Part - time jobs are mistakenly thought by some to not be careers. However, legislation exists to stop employers from discriminating against part - time workers so this should not be a factor when making decisions on career advancement. They generally pay more than part - time jobs per hour, and this is similarly discriminatory if the pay decision is based on part - time status as a primary factor. The Fair Labor Standards Act (FLSA) does not define full - time employment or part - time employment. This is a matter generally to be determined by the employer (US Department of Labor). The definition by employer can vary and is generally published in a company's Employee Handbook. Companies commonly require from 35 to 40 hours per week to be defined as full - time and therefore eligible for benefits.
