Herme works as a teacher with severely disabled students in Alberta. The Alberta Teachers$$ Association has been bargaining for the past six months, and it seems as though a strike is on the horizon. Herme thinks she should be classified as essential because her students have unique needs. A strike would be extremely disruptive for them, and there could be long$-$term impacts on their learning and development. Furthermore, this is a specialized field, and it is unlikely parents could find suitable alternative supervision in the event of a strike. Is Herme an essential services worker? What are the criteria for deciding whether Herme should be classified as essential? Based on Employment law for business and Human Resources Professionals, Albert and British Columbia, $4$th edition
