Additional comments: -

When you write instructive letter or warning letter, we need not request or write words like "kindly". Secondly, when the information is not received even after the "warning" then it goes on to show how insensitive the recipients are. This is a reflection of weak leadership or organisation's culture. While these disciplinary measures may sensitise someone, it will only have temporarily effect. Sometime, you have to address the larger issue of cultural change.

Thanks,
