セクハラ (せくはら, sekuhara) is an abbreviation of “セクシャルハラスメント (sexual harassment)”. Compared to the English term, セクハラ can be used more casually and describe unwelcome sexual conduct that is either serious or somwhat trivial. For instance, it might be regarded as sekuhara if you are too friendly to your male/female colleagues at work, e.g. by hugging them, calling them with their first name, or frequently giving compliments about their appearance.
パワハラ (pawahara), アカハラ (akahara), and アルハラ (aruhara)
After the term セクハラ has become prevalent, some Japlish (Japanese-made English) words have been coined to indicate different types of harassment. That includes “パワハラ” (pawahara), “アカハラ” (akahara), and “アルハラ” (aruhara). The first word パワハラ (pawahara) stands for “power harassment”, and indicates the general abuse of authority, such as a physical or verbal attack at work or school. “アカハラ (akahara)” stands for “academic harassment” and indicates abuse of authority in academia (e.g. harassment to students from their supervisor). Lastly, “アルハラ (aruhara)” stands for “alcohol harassment” and indicates the act of forcing someone to drink.
