You mentioned bullying as an example. See, we're coming back to definitions. How would you define “bullying”?
We've heard different stories of what bullying can be. When we've gone through our training here, if somebody wants a day off because they want to go wherever, and it's traditionally not a time to take a day off, and we say, no, you can't because we need you to be here, some might interpret that as being a bully because you're not giving them what they want.
This is where the problem comes with definitions. Once you've set it in legislation, now you're stuck with it.
