I presume you are referring to sekuhara (sexual harassment), pawahara (power harassment) and the like

[raffraffraff]

Are the actual official Japanese words for sexual harassment and power harassment... just Japanese pronunciations / abbreviations of the English terms?

[lmm]

Yes. In Japanese this kind of abbreviation does not carry the childish/frivolous connotations it does in English.
