Didn’t Disclose Current Employment to New Employer

I recently accepted a position with a larger company while still working at a small startup. During the interview process, they didn’t inquire about my current employment status, and I chose not to mention it, as my previous role was more relevant and impressive for the position I was applying for.

In the past few years, I have changed jobs for various reasons—like relocating from the US to the UK, which prevented me from transferring roles. This led to concerns from the interview team about my job-hopping tendencies, but they ultimately decided to move forward with my application.

Now that I’ve signed the offer, I need to provide my current employer’s details for a background check through HireRight. This means my new employer will discover that I’m still employed, and I’m worried they may rescind the offer since I didn’t disclose this information.

I see a few options moving forward:

  1. Email the Recruiter: I could reach out to the recruiter before notifying my current employer. In the email, I would explain that I didn’t think my current job was relevant and wasn’t sure it needed to be included in the HireRight form.

  2. Submit the HireRight Form: I could give my notice and send in the HireRight form without any explanation to the recruiter. However, this poses a risk if they decide to terminate the contract once they find out.

  3. Omit Current Job from HireRight: Although this feels uncomfortable, I’ve read that they typically only verify the information provided. However, I’ll also be supplying a P-45, which outlines my complete employment history.

I’m unsure how to proceed and would appreciate any advice.
