Need help or sharing from sifus here..

I currently work in an oil & gas MNC, but I am planning to resign because of some family issues and might take about 2 months break after resignation.

My question, is it advisable to do this if I plan to return to O&G field or just engineering field in general? Some of my peers suggested me to find a job first before resigning because a gap in my resume might be a warning sign to potential employers in the future.

I have a little bit more than 3 years experience in this current company, holding different portfolios and worked in different branches.

Thanks in advanced.
