Case study; your manager lost important document in your absence (as employee resignation) & the count started for 30 days notice?

Defending your honour will not accomplish anything.Rather rectify the situation , ask employee to write another letter dated the date of the actual letter.However when submitting letter to manager be honest about how you got the letter.

It is always a good policy to make copies of important documents that is one of the most important things that I have learned in my professional career.
Keeping a back up of important files is always essential and will save you a lot of heartache in the long run.
If there is no back up and your manager lost it and you are absolutely sure you did not misplace it, I don't believe you should take the blame.
If you take the blame one time you will take the blame many more times.
To me integrity is key.
Being true to oneself is important.
For me I couldn't take the blame for something I did not in good conscience do.
If that means I no longer have a job so be it.
I realize that if someone is dishonest enough to pin something on you and not big enough to take responsibility for their own mistakes it is only a matter of time for life catches up with them.
There are some things in life that are more important and one's character is onen of them. 
 

Am I going to be held responsible??? Nonesense.....
if that manager could not reserve a single document then he come he is a manager??? We have as a team to first look for that particular document, then I wonder where is the role of the HR team??? Should not that resignation be with HRM in the first place??? I am not to be blamed but that Manager is fully responsible for that along with his office in charge.

Any situation creats any Co-ordination, How the sales coordination make super sales, sameway if my  Manager have coordination with his team or I have the coordination with my team and Office or to that subjected team, there will be no problem even if I lost the documents.
Every problems has the way out, it opens when you have good coordination.

It depends upon the type of document he lost.
Be it an employee resignation then it can be taken again dated back.
If its duplicate copy can be obtained in case of any other document, try to go for it.

When someone resigns then the first thing to do is to forward all documents, duties to a person in charge, and he or she can't get final salary or experience certificate without confirmation from the person in charge that he or she took everything related to work, so such case will never happen.

I would suggest if you would approach the resigned employee and ask him/her if he can write a new resignation letter in a company format and sign it marking it with the same day of the initial resignation letter; As he resigned I don't think he will refuse to do so And this will close the case

first of all I will try to search for the lost paper in the places I know my manger is used to leave things at (usually the managers who are used to lose things they do that in the same places everytime) I will start search in his drawers, his suitecase, his car or the last places he was seen in "other offices" a last try i will call his wife as ask her to search at home "as I have good relation with the boss wife :').

If the document is not found i have no other choice but to ask the resigned employee to come over and write a new resignation dated back to the time he submited the resignantion.

 

ask the employee to provide the copy of his resignation, give the copy to your manager to sign and mention original was lost,if the employee lost the copy too you can ask him to resign with the same date of previous resignation , give him the copy and mention on the copy that you have received the original , receiving resignation with the same date twice will not make any trouble for your company , scan the document and keep it as soft copy in the employee file folder.

I will accept my mistake because I am responsible for that, this was my mismanagement. I should make copies or scan such kind of important documents. 

Here is where good organisation skills comes in; If important documents are to be handed over to other senior person / manager; its better to have a note on the date you have sent them and better with an email acknowledgement to follow through. This habbit  will keep you away from unncessary stress. If photocopies can be kept; always make one set and keep it for your own record. This way you will have all the backing and can have a good night sleep.

If you haven't any record, you might become the victim of circumstance;
