Is sexual harassment part of workplace harassment?

Yes, and it is a prevalent one as the #MeToo movement has demonstrated in recent years. In Ontario for example, the Occupational Health and Safety Act was revised in 2015 to include workplace sexual harassment along with the definiton of workplace bullying and harassment, and other provinces maintain a similar standard in their occupational health and safety laws. 

Similarly to other workplace harassment, sexual harassment may not be as obvious as some might expect. Inappropriate jokes, leering glances, and unwanted touching may all be more obvious and straightforward examples of workplace sexual harassment. There are however even more common subtle forms, such as unwanted and repeated affection or attention, unwanted compliments or attempts at flattery, or repeatedly attempting to ask out a colleague all constitute workplace sexual harassment as well. Also this is not exclusive of any gender – individuals may perpetrate workplace sexual harassment no matter their gender identity or expression, or sexual orientation.
