House elves strike lasts 11 days because pleas were denied.

Between May 21th and May 31th, house elves stopped their work at Hogwarts. Lead by Hermione Granger, the elves are requiring better work conditions by stopping their tasks in school.

After Harry Potter gifted Dobby with a sock that set him free, a wave of demands started to happen from the other house elves, this caught the attention from one of the students, Hermione Granger. She used the app whatsapp to convince all the other elves to joing the drive and that is the reason why the negotiation took so long.

According to the head of the strike they tried to solve the problem by talking to the directors of the school but they did not get into a consent.

As a result classes were canceled because the school was not able to provide services like feeding and cleaning. Teachers, students and the directors of Hogwarts were outrageous.

After some days of talks the elves decided to accept the new terms that were 15 hours per day, 7 days a week , and also a punishment for the students that show any disrespectful behavior.
