Tier 2 gap in employment

[tripaths]

I am on Tier G visa since Dec 2016. I have a potential offer from another employer in UK but due to noncompete reasons I will have to switch to a third employer before joining them. I am evaluating the possibility of joining a 'dummy' employer in India and then make a fresh Tier 2 G application under my new UK employer.
My question is that lets say it takes 3-4 months before I am back in UK on Tier 2, how will this impact my and my dependant's ILR? Will it be reset?

Also on a related topic, I am in UK since 2012. 3 yrs on Tier 2ICT then 1yr on Tier 2 G dep and then 2.5yrs Tier 2 G. Will ICT and dependent period count towards 10yr continuous residency rule and again does this rule allows for 2-4 months break in residency/visa?
Thanks

You cannot be away from the UK for more than 180 days in general. As far as I know TIer 2 visa has cooling off period of 12 months.
If you leave with a valid visa and then return within 6 months your long residence period will be intact.

Thanks. Understood. I thought cooling off applies only for Tier 2 ICT only but def that's not the case.
I am reading that there is a high earner category on which cooling off doesn't applies. Is it true ? Base salary threshold is 159k or 120k?

Higher threshold of £159k.
