While city council won't investigate Denver Mayor Michael Hancock for texts he sent to a subordinate,

city employees are being told not to commit sexual harassment because it's "illegal."

All employees are being required to watch a training video about what constitutes sexual harassment and how to handle it.

The video - which Mayor Hancock's spokesperson confirms he has watched, even though the mandate does not apply to him - is just over 11 minutes long and is loaded with dos and don'ts.

9NEWS obtained a copy of the training video. It starts with the city attorney, Kristin Bronson. "This is a serious topic that requires all of us to understand it and how to prevent it," she says.

The video goes on to define what sexual harassment is with what seem like common-sense definitions.

The video outlines what could happen if someone is found to have sexually harassed someone, although, as we've talked about before, the mayor is unlikely to face any serious consequence unless voters decide he shouldn't keep his job if he runs in the next election.

The video goes on to explain the types of sexual harassment: quid pro quo and hostile. Then the video explains when, where and how sexual harassment can occur.

And then, it mentions, "Texting or sexting sexually explicit messages or pictures via a cell phone."

Employees are told to immediately report sexual harassment to a supervisor or human resources, and the video ends with some serious remarks.

"Besides being illegal, sexual harassment creates an unproductive, unpleasant, and sometimes even

an hostile working environment."

The city insists this video was planned months ago, before the mayor's accuser came forward.
