Meri used to work in a medical office. When the show started airing, there was an episode where she commented that she was let go because of the show and her beliefs.

Now, she is a very successful Lularoe consultant/seller/whatever they are called. I am a part of her group on Facebook and have bought a few Disney themed items of clothing from her to wear on my Disney trips. Where other consultants have marked down their prices on several of their items, she rarely has to because people will buy them at full price and, believe me, they aren't cheap. She travels frequently with fellow consultants/friends so she's not just sitting home and sulking over where to build her house. And, then there's the bed and breakfast that she owns. I don't know if it makes much money but I'm betting that folks book just because it's owned by a "celebrity".
The last time that I tried to go on the My Sister Wife's Closet website, there was no inventory/items listed and it said to come back soon. It's been quite some time since I've looked so it may be back up and running. ***While typing, I got curious and went to the site....still the same message.

From what I can recall, Janelle has made several remarks that she was one of the wives that has always worked and that she enjoyed her job. She has a website:
https://strivewithjanelle.com/ and if you look at the merchandise that's offered, several items are sold out. She also posts on Instagram that she signed up for FabFitFun which I am sure gives her some sort of money for hawking their wares.
I don't know if Christine has ever worked outside of the home because I don't remember her ever mentioning it. Like someone said above, she did get her realtor's license a while back so maybe now that her kids are older, she may get into the real estate business.
