Should both partner's in a relationship make an equal effort?.

It takes two people to make a relationship work. So my question is: Should both people make an equal effort?.
Is it ok for one person to keep texting and calling the other person and making all the plan's?.
Is it ok for one partner to go 'awol' for day's and not make contact?. Is it fine for one person to take the other for granted?.
Is it really a relationship if it's just one person making an effort and the other person just sitting back and letting them?.
