Interacting

Talking to women in meetings

Q: As there are women in all working environments in today’s time, if we at work are sitting in the same board room around the same table as women and we sometimes have to talk to women in meetings etc. are we sinful for this as there is no purdah in the boardroom as well as we are talking to na mahram women?

Woman not observing pardah with non mahram males

Q: A woman doesn't observe pardah (covering her face). 

She works in a home. There is a man and a woman. The man observes pardah from her. When she comes to work, she comes walking and without pardah. The employees have tried to encourage her to wear pardah but to no avail. 

Now she is offered a job at another place. There it is not clear who she will come into contact with. 

My question is, if a person suggests for her to take the job, is the person sinful because she will come into contact with men. She isn't observing pardah, she is also leaving the house to come to work, so on the way she is going to come across men.

Keeping a non-mahram as a Facebook friend and conveying salaam to non-mahrams

Q: 

Can I keep a non mahram as a Facebook friend? If I don't talk with them unnecessarily & don't post any photo of mine? Will it be considered as zina for me? Can I give likes to the posts of non mahrams or will it be considered as zina? 

Can I give salam to my non mahram relatives? Will it be considered as zina?
