Hi Lorcana
Well women take long maternity leave for a number of reasons, one obvious reason is bcos they want to spend time with their baby-the maxiumum time legally possible. If the law was 6 months at most, women would take just 6 months. If it is there why not use it. I do not think they should shorten maternity leave to less then a year. I think we should also look at the Swedish way of thinking and a study says they also have the happiest kids. A job, one sort or another is a life long thing, but the baby you have just given birth is a once in a lifetime opportunity. That baby will never be a baby again etc. Also, it may be the the woman has had an c section, complications at birth and it takes time for a woman to recover. I think it takes a woman with c section 6 months at least to recover or longer if other complications.
Another difference is you probably get paid alot more then your staff....so you might feel there is alot more to lose career wise then the staff you manage. Maybe they feel they are not progressing their career. I might be wrong of course.
As a manager, you can make it so these staff do not come back demotivated and out of the loop etc - you can keep them updated without intruding, see if they want to use keep in touch days. Maybe you need to ask yourself whether it's your management skills that is causing this. It might not be and that you're a great manager but it's something to think about and internally ask yourself.
Also,you took 4 weeks to 3 months for each child. I am wondering why you only took 3 months at the most for maternity leave? Was it the career aspect, money? I've always wondering why women take short maternity leave?
Hope this helps answer your question:)
