Such ethics are required from every citizen. Though it is accepted that suspension is not a punishment, it is more than a death to sensitive citizen. Only, if there is a doubt that he tampers the record and influences within organisation , suspension may be a reason. But in case of any allegations, suspension may not be the right way, though nothing stops employer, and a good HRD can never resort to such ultimate step. There may be several things involved in deciding good moral conduct and such law in private life and evidences.
It is true that in many organisations, where victimisation is prevailing even before issuing charges, suspension is effected, and as informed already it is not a good HR practice.
