One of the reverse gear advancement in the millennium that we as civilized humans have made is that most of us don’t take warnings seriously anymore at least the oral ones. This is what escalates the importance of written warnings. Because these days we want everything in black and white and otherwise don’t give a damn to what is being said, a free of cost suggestion for you is that if your employees are not taking you seriously, your renters are not listening to you, your student thinks he is okay with the grades he make or whatever the problem there is that you’re trying to solve, try writing warning letters for that.
Warning letters used to warn a person of violation of rules that he/she might be doing, a delay, an inappropriate behavior or any other inappropriate dealing of a matter. Warnings are a pre-announcement that unless the addressed matter is corrected, serious action will be taken over it. There is specific sphere where warning letters are being used. They are used everywhere to deal with misconduct and misleading. In business, in academics, in general by government or other authorities and even by common people as in the case of a renter and landlord where sometimes landlord warns the renter to follow the contract by sending warning letters.
Another advantage is that writing a warning letter is a decent way than to warn face to face that may possibly go harsh and un-mannered. You may not get convinced about the efficiency of warning letters so easily so better you try it yourself. Think of the person you warned last time and he hasn’t yet corrected the mistake write a warning letter this time.
I can hear you saying that writing letters take time and someone else from the other end loudly saying he doesn’t know how to write a letter at all. Who asked you to write it all by yourself? You can look for some online letters and trust me you’ll find many there defining your problem aptly if it is a typical one. All you’ll have to do is to make minute edits and your letter is ready to fire at that non serious teaser. Three, two, one Fire!
