Not sure I understand. My husband got his Irish citizenship about 4 years ago. He got it because he could and because we had spent a year in Spain teaching, but could not remain once our student visas expired. He wanted more options for living abroad.
The rules are different. There are the UK immigration rules; EEA Regulations and European Court of Justice Rulings; and there are two sets of rules for Irish citizens; depending on if they have lived in their own country, the RoI/last entered the UK using the CTA, and that's what I was talking about.
He has been diligently looking for work since before we relocated to Colchester, UK. He has had one interview and on just about a daily basis is submitting applications for vacancies and walking to different shops. This is a very different process than what we are used to, and my understanding is that it does take some time. He is trying to find a job ASAP. Any advice anyone has would be welcomed.
As he is using the EEA Regulations to sponsor his non-EEA citizen family members, then he must follow that Free Movement of Persons Directive 2004/38/EC, at all times. That Directive allows him 90 days in the UK with his family members and after that, for you all to remain lawfully in the UK, he must be what that Directive calls, a "qualified person". He must then follow the EEA Regs at all times after that, for you all to remain lawfully in the UK, usually that means being a "qualified person".
An EEA citizen has a time limit to look for work in another EEA country and after those 90 days, they must leave and can look for work in another EEA country instead- unless they become another type of "qualified person".
This is the link I gave you before when you were talking about moving to the UK and both you and your husband need to read this. It's important that he must follow these at all times for you, your daughter and niece, to all to be lawfully in the UK. Even an Irish citizen can be unlawfully in the UK.

RC cards become invalid
Time spent unlawfully in the UK can also be a fail of the UK's Good Character requirement for citizenship. For Brexit, the UK has already said that any offer to stay after Brexit, is only for those lawfully in the UK
There isn't just a "worker qualified person". If you look at what Nan is doing, she read that Directive before she moved to the UK and has made sure she is already being a “qualified person” (is exercising her treaty rights already) while she looks for work. Now nan doesn’t have to worry about her 90 days allowed. She is being a "Self Sufficient qualified person" while she looks for work as she meets those requirements - can show the finances to prove she can support herself and her family members, has brought Comprehensive Sickness Insurance for herself and her family members and will not take UK benefits. When nan gets a job that is "genuine and effective" then Nan can be a "worker qualified person": that way, her stay in the UK and that of her family member, is always lawful.
