Honestly, the way you feel about mat leave laws/women (and they're the same thing; your splitting of women as a class apart from your stance on ML is false, and sophistry) is howlingly clear from the language you consistently use.
No. You keep doing this but you're just as wrong now as the first time you did this. I have no truck with women. I do have a problem with anti-business laws. I have a problem that as an employer I should be held responsible for personal choices or at-home well-being of my employees.
To me this is a straightforward transaction. I pay, they work. Just as if I can't pay, they won't work, if they can't work, I don't pay. Simple.
I have the same problem with not being able to replace a male employee if they go on long term sick leave. As much as I feel for them on a personal level, sorry, but this isn't my responsibility.
Fine. Great. You'll get someone grand. Maybe someone who likes short-term jobs for their own reasons and, because they don't have the security of a salaried perm job, has worked harder and better than a lot of people and is super-skilled and experienced. Or maybe someone internal, moving sideways or acting up temporarily; in which case, down the line, with their new skills and experience, they'll be of great value to the company.
If this is an option, great. But as has been pointed out by PP it often isn't. I don't mind trying to accommodate a valued female employee, but if it's too much hassle, I shouldn't be held over a barrel.
If you're 'muddling along' then you have not recruited, trained or managed very well. Nothing to do with the ML person or, indeed, anyone filling the job.
If it 'hobbles your business', again, that's all about your business.
Be that as it may, I still shouldn't be forced to keep the position open for a year.
And 'humankind survived quite well'. Did it?
I replied to a poster who claimed making it difficult for women to have babies will result in their being a dearth of eligible employees some years down the line. I pointed out that history tells us otherwise.
And as I've previously written clearly and at length, I have no problem with government supporting women during and after pregnancy, to help them overcome this natural hurdle.
But this should be a collective burden, not one shouldered by individual employers by luck of the draw.
