Dear Rakhi,
Show-cause doesn't have specific formats. It depends on a case-by-case basis. You have to draft a show cause notice based on the actual facts, reports submitted by the reporting officer, time, and the damage caused to the particular subject. The language should be as simple as possible. If issuing to workers, then you may have to translate it into their mother tongue or the language understood by them.
In case you are doing translation, you should insert this line at the top or bottom of the letter as follows: "For official purposes, the letter dated... reference no.... issued to you will be held valid for all purposes. This is a simple translation of the aforementioned letter issued to you."
It is advisable to show your show cause notice to your company labor advisors before issuing them because in many cases, the show cause notice becomes the basic document for further disciplinary action.
After issuing a show cause, you have to complete the cycle by closing the case, creating necessary records, and keeping a copy in the employee's personal file for future references. In case the employee admits guilt, then you can close the case with a stern warning.
I am enclosing a draft of a show cause and warning letter for your reference. You can use it for different subject purposes as explained above.
I hope that you will find my inputs useful for your needs.
Regards,
Ashish
