Working for a large firm has its perks. Aside from the salary, you get to set your own hours, take unlimited vacation, even go on parental leave when you have a new child. Good luck taking advantage of any of that, though. Billable hours tend to trump all else.
Lawyers who are new or expecting parents often find that, in the firm's eyes, the work-life balance should always tilt towards work. Fathers in particular face extra pressure to put work before family. But for dads who want to be present at the start of their children's lives, taking parental leave is difficult, but not impossible.
