Hi Maha,

Here is the difference b/w the two....

Once you got the information that a particular / Group of employees involved in any indiscipline activity then framing all the charges under the Model / certified standing orders applicable to the organization the charge sheet will be issued asking the individual employee to submit his explanation with in 48 hrs / 2days / 3 days etc., hence the process starts with Charge sheet.
Once the management is not satisfied with the explanation of the employee then they can call for a Domestic enquiry, once the enquiry is completed and the enquiry submitted his findings to the management and basing on the report submitted / finindings of the enquiry officer's the management will issue Show cause notice to the employee mentioning the proposed punishment, even if it is a major / capital punishment the management will issue a second show cause notice also giving more opportunity to the employee. Hence all put together the charge sheet is the beginning and followed (if required only) show cause notice.

Hope it's clarified..
