昼休みにランチに出た新卒社員が消えた？ 先輩社員は呆然、入社日に「即退職」は許されるのか（弁護士ドットコムニュース） - Yahoo!ニュース

This page discusses a case where a new employee disappeared after lunch on their first day of work, examining the legal implications. According to a lawyer, employees with indefinite-term contracts can resign by providing two weeks' notice, while those with fixed-term contracts cannot typically resign mid-contract unless there are unavoidable circumstances. In cases of unauthorized absence, companies may claim damages, but proving concrete financial harm from a first-day afternoon absence is typically difficult, making successful claims unlikely.
