i dont get it
the common approach for treating depression is a combination of anti-depressants or something with SSRIs (selective serotonin reuptake inhibitors) and group therapy to adress the issues that cause feelings of hopelessness. not a short dance followed by an angry outburst. also i dont think management would approve of employees dancing on the tables, plus kicking a plate of food into someones face is considered harrassment he should talk to his supervisor about disciplinary action for the other guy.
