Well it's a really strange decision. Your company has decided to have networking, but you haven't decided to have networking with it's most fundamental functions and requirements to work in the long run.

DHCP is a very basic function for networking. It also included functions like lease expiration. If the DHCP server cannot be contacted, the client sticks to it's current lease for X days, usually set somewhere between 3-7 days.

So actually, the motivation that DHCP should cause an instable network is actually as wrong as it can be. Basic networking functionality that usually have less stability is DNS and gateways/firewalls. And see where you are now, you need to change DNS-servers If you'd had DHCP, this wouldn't have been a problem at all.

I strongly suggest you go to your boss and say he's wrong. Send him here if he thinks he knows better
