It's good that at least here you've a note about a kicked garbage can. I once searched for something, anything that was a written law to add to one of our contracts years ago. It's a Violence in the Workplace clause. I cannot find where I sourced it from, it was a federal agency like the epa or labor, but the words were what was being experienced by many. What you've described is intimidating and disrupting behavior and note worthy.
Of course you were shaking. We all deserve to work with dignity.
Did you get your shift changed?
