The incident happened in November 2017, from feb 2018 I am under suspension, They set an internal inquiry by a bank officer, during its hearing there was no proof of theft nor any witness which can prove my guilty, on his report the inquiry officer wrote that all aligations were malafied, but under management pressure he wrote that the charges are procedure. Now on behalfe of that report, bank has terminated my services. I want to challange this termination in Nainital high court, I want to now that the process how to challange this. Thanks in advance.
