they perform random checks or checks when something looks suspicious,
so there is only a small chance they would contact your employer, also it will probably be 2 months before anyone even looks at you app, so you'll be in your new job by then.. so if they do a check, you can give them your new employers details, or if your the worrying type, when you start your new job, get your wife to contact the embassy with your new employment details,,
but if i was you, i wouldn't bother at all, i'v e been thru this, didn't have a problem
oh forgot to mention, ive applied for a few visas over the years, and i know my employers have never been contacted, as i've asked them each time
