In every business I have run, I have done it with absolute respect for the rights of my employees, and that includes managing maternity leave.
If you do not have a mechanism in place to facilitate leave for life events for your employees, then maybe that is a level of contingency that you should look at adopting, then you would really be able to employ the right people, not just the right men/childless women.
I have worked those shitty jobs, pre-minimum wage, and built up a very healthy disdain for what it is to be employed by companies/bosses that see me as nothing more than a resource and as a result, all of my businesses have been profitable, and I am incredibly proud that I have managed to do that with my integrity intact.
The law is there for a reason. And Women deserve the same rights to employment as Men. There is no leeway on that point if you are truly a considerate employer, or indeed a considerate human being.
