UK - security clearance and over-employment.

I know there is no way out of this. Just looking for an insight.

So long story short, my company are dropping people and I’m scared of being next, so to avoid this situation, I’m applying for a second job.

I’ve gone through the interview, and I’m awaiting a response now.

If I got this job, great. I have job security. I’ll be working both jobs until I get made redundant (maybe I won’t).

My concern is when I interviewed for my second role, they mentioned I could potentially work with the MoD, resulting in getting SC.

Problem? I can’t hide my first job, but if I admit to it, big issue. I read my J1 contract, and it does not mention anything opposing additional work.

I see no way out of this. Even if I found out months prior to getting SC that we require it, I would drop my first job. Still, they’d find out about my overlapping employment.
