Modern Challenges in the Labor Market

The Qualification vs. Experience Paradox

Nowadays, many people possess high qualifications, often holding multiple university degrees. However, companies frequently prioritize candidates with more experience over those with high qualifications. I believe this creates a significant barrier to entering the current labor market.

The Life of Irena Sendler

A Holocaust Hero

Irena Sendler was 29 when Nazi forces invaded Warsaw, Poland, and began imprisoning Jewish people in ghettos. Before this, Irena grew up with strong morals and kindness in her heart. She believed that no matter a person's ethnicity or social status, they should always be treated with kindness, respect, and love.
