I worked for two years at company
ABCD, a decade ago. Around three years ago they changed their company name to
HIJK. I verified that they had changed the company name, and had not closed
ABCD and started a new company because
HIJK is listed on the Ministry of Corporate Affairs website with the date of incorporation shown as 2006.
For the past few years I've mentioned my previous employer in my CV as:
ABCD (now named HIJK) [Feb 2009 to April 2011]
I've worked with them recently for a few months on a contract assignment and things didn't turn out very well (I'd rather not mention the reasons, but it was basically neither their fault nor mine, and we realized that I'm not a good fit for their company culture, so we don't plan to stay in touch).
In future CV's, I don't want to mention HIJK as the company name, as I'd prefer any background check person to not contact my previous employer, in case they lie about me just out of spite (nothing that bad happened, but just-in-case).
Since my old offer letter and employment agreement mentions ABCD as the company name, is it ok for me to mention ABCD in my CV and pretend that I don't know about the company name change or is there an ethical need to mention HIJK?
