In Pakistani corporate environments is considerations made for people with multiple spouses?

Non-Pak resident wants to know

Such as, if office throws a eid party, and boss wants to get an approx count of people for catering, is it just assumed people will bring one wife only? Or do they think what if someone brings four wives?

What if someone tells their boss they have to leave early because third wife is not feeling good?

How about work provided benefits, do they include upto four wives coverage for medical?

Does tax system include tax break for multiple wives?
