If you've left a private job without notice and are now applying for a railway position, you're concerned about how this will appear on your attestation form. While employers generally have the right to verify past employment, government departments like the railways typically focus on criminal records and essential qualifications rather than private sector work history. It's advisable to disclose your previous employment truthfully if asked, but it's unlikely to negatively impact your railway job unless there are specific concerns about your conduct.
