The issue you may observe with an all female work environment is that your wife is exposed to a bit much feminist go girl rah rah crap. Bad attitudes. This you have to be mindful about. You want your wife to appreciate what she has with you as a husband and father and head of house.
Just want to add this issue isn't exclusive to a work environment , her friends and even acquaintances can be equally as toxic and you need to screen them as much as you do her
I have a friend who takes this too the extreme by actually accompanying his wife too her girlfriends social engagements I think to keep an eye on the topics of conversation
whilst I wouldn't do this and I find it a bit weird I can see his concern
There's not many women out there whom are in correctly polarised relationships and are completely happy / content some are more than happy to start corrupting other's as a result
I often say this but women are like water they will go in whichever direction a strong current takes them
You must dominate your womens mind , constantly impress your expectations and boundaries dont just assume that because you have been together a long time she couldn't be swayed into a new perspective or line of thought ( which lets be honest is were all disrespect starts )
LTR's are very complex you sort of lose the overriding desire for each other in day to day monotony ,the desire and drive for sex starts to wain for both of you and its very easy to take your eye off the ball
Before you know it , it can be all over
