In your opinion, is it healthy to work with your wife at the same company?

NO , this will cause lot of PROBLEMS

why not :)

sure

بالتاكيد لا الوضع مش راح يكون مريح 

Nope not at all its not healthy because its not easy to see your wife as a man talking to another man course you might not know weather its business or personal. In my own opinion I rather work far from my wifes company not to see what happening.

It depeneds on this couple if they can work togther or not,

but for me its not good to work togther because its always causing problems.
