Malala Yousafzai is a famous activist for education of young girls who the Taliban attempted to murder for her activism. Hence her comment "Boo 👎" on this young girl's post about skipping classes.
Young girl is just shocked she got called out by a famous person.
"Unions make people lazy" "Unions make people less creative, less likely to work to fix problems" "Unions make employees fight with each other" "Unions mean we'll earn less money"
The propaganda I've heard from older generations is really incredible. We're still actively unionizing lol
