All related misconducts could be combined in one SCN.
For ex: Habitual late coming, unauthorised absence from duty, irregular in attending duty, absence from the workplace after PUNCH IN, Sleeping while on duty etc.
Misbehaviour with peers/superiors, manhandling/physical assaulting supervisor, quarrel with other staffs, consuming alcohol while on duty, forgery etc.
Please note that some misconducts are light in nature while some others are grave. There are some misconducts for which an SCN could be issued and after receipt of written explanation, the matter could be closed after issuing a warning letter; while some others need further disciplinary procedures, like issuing a Charge sheet or Charge sheet-cum-Suspension Order, after receipt of written reply from the delinquent employee, ordering domestic enquiry, awarding suitable punishment, etc..
