I recently started working for a company after graduating. In a month I found a better offer from another company. I quit my current company and nor did I disclose this information to my new employer during interview process or in my resume.
I got the contract from my new employer along with a personal information form which asks for information such as tax class, marital status and so on. There is also a section asking me to fill out information about my previous employers.
I do not wish to disclose this information as this might lead to bad impression about me in two ways. One, me not disclosing this information earlier. Secondly, new employer might lose trust in me knowing I quit a company in a month.
Can I choose not to disclose my previous employer information? Is there any way my new employer could find out by other means? What are my options here?
