I have been in my current job for less than a year. Near the end of last year, I was contacted by a recruiter for another company and went to attend the interview.

I've just been contacted by the recruiter who informed me they would like to offer me to join them with a 10% increment from current job. However, they need to conduct background checks and there is one part I may have trouble with, which is that I have a 8-month gap in my employment history due to being retrenched from my first job and I took some time to rest before finding my current job.

I don't have a proper offer letter from the other company yet, only an email summarizing the offer and requesting for documents to submit for the background check. Should I start to discuss with my current manager/team lead about this offer? I plan to accept due to getting to learn new stuff + higher salary.

Thanks, I've gotten the offer letter for now. Will probably discuss resignation from current company after CNY bonus payout, luckily the offering company willing to wait for me.
