I offered a really attractive remuneration package for the very reason that I don't wish to have to go through this again in the very near future. But to do all this for a temp replacement, I'd find that extremely unfair.
You haven't addressed the ideas raised in this thread of having an existing staff member act up for a while (which would be less 'hassle' as presumably they'd be at least partially trained for the role); or the fact that specialised agencies exist, with people on their books who would be more ready to step straight into highly skilled positions.
Because in practice this is often not feasible. In my business, there is no one who could step into the role of the main skilled workers full time, though I could get by for a day or two if the key worker called in sick. And I think you overstate quite a bit the availability of temps in specialised agencies.
As I wrote, my recent new hire was a huge hassle and took up many hours of my time.
I'm all for hiring the best candidate, I just disagree that I should be obligated to keep a position open for 6-12 months for someone who makes a personal decision to have a baby. Why should it be my responsibility to ensure she has a job if and when she decides to return?
The way I see it, I hire someone to do a job, I'm obligating myself to pay and they're obligating themselves to work. If they decide to leave, well they're not my slaves, so I wish them good luck and we part ways.
Everyone understands that if a worker decides to take a sabbatical or a round the world trip, I am not obligated to keep their position open for them if and when they return. I might decide to do that voluntarily, because they're such good workers, but it's neither a moral nor ethical duty.
So why when that worker decides to go and have her baby - something that is entirely her choice and doesn't involve me in any way - is it suddenly my duty to keep her job waiting? How have we switched from a simple contract of labour for money, to a duty to care and support her in all her choices?
And to those saying it's good business practice, so is service with a smile. But that isn't enshrined in law.
