Is egg-freezing birth of new worker right?

Google and Facebook will pay for the process so female employees can delay childbirth and prolong their careers, but is it ethical, asks Sharon Ni Chonchuir.

IT’S easy to envy Google employees their free lunches, yoga classes and transport to and from work. The latest office perk is egg-freezing. Google and Facebook will pay for female employees to freeze their eggs, prolonging their fertility, while giving them the time to find the right partner, focus on their careers and choose when to have a family.

But is this progressive? Does it level the playing field for working men and women by beating the biological clock? And is egg-freezing a viable option for women who hope to have a family one day?
