どうせ有休なんて取れないんだから買い取ってくれればいいのに、って思ったことありますよね？実はそれ、法律違反なんです。だって、買い取ってくれるって分かってたら、休まずにお金もらっちゃうでしょう？退職時のみ残りを買い取り可能となっています。
Many Japanese office workers are entitled to annual leaves 18 days a year on average but only half is consumed. The workers wish that their employers would buy up the untaken leaves but it's illegal to do so. The employers have to buy up the leaves only if the employee wish them to when s/he is leaving the company.
