Please be aware that just by summoning a person to the police station u/s 41A of cr.p.c. for inquiry into the complaint made against him will not be deemed that he is guilty of charges or that he has been arrested or remanded.
It is not necessary for the employee to inform his employer even if he is remanded and released on bail within 48 hours.
The department may initiate action as per CCS rules or any other prevailing law only when the employee is convicted and sentenced to undergo imprisonment.
Section 41, 41A, 41B of CrPC govern arrest by police without warrant
These sections were modified in amendment to Cr.P.C (Criminal Procedure Code) in 2010 to minimize abuse of powers of arrest by police, especially in cases like IPC 498a, which being a cognizable offence didn’t need a warrant for arrest.
Though the rule to inform the employer has been mandated vide the above letter referred blind eye to such incidents i.e., arrest on pre-trial and being released on bail subseuently.
In your case you have just been summoned, hence it is not an arrest. In practice even the authorities turn a blind eye to such incidents especially when this is due to the matrimonial disputes and wait for the final decision by court to initiate suitable departmental action if necessary.
