Sure. Any coasting or slacking is just as likely to have been done by a female employee as a male employee, so it's a false dichotomy in the first place.*
Which is why a competency based recruitment process is far more effective that just looking at 'time served'
But generally speaking, the number of years' experience, tells you something about expertise
But not always and it is a very crude tool which relies heavily on assumptions.
If I need a good bricklayer, or an experienced mechanic, I might specify a number of years' experience in my job-vacancy ad. To pretend that there is no difference between someone who did the actual work to someone who took care of a baby, is ludicrous.
That's not what were doing this is it? You are assuming that women who have taken maternity leave are less competent at their jobs which really is ludicrous! An be careful specifying a number of years experience as that could leave you open to accusations of age discrimination.
But on the subject of answering specific questions, can you please address the point I made of a collective obligation being placed on the individual. Employer A has no more obligation to society than employer B, yet the arbitrary matter of A hiring a female employee and B hiring a male employee, means they need to carry a far larger burden of the societal obligation. Why?
This has been answered numerous times by a number of different posters. Either you don't understand or you're being purposefully obtuse.
And the second point, which hasn't properly been addressed - actually subverted, with the invariable reply about a man also being involved in the pregnancy process - is why an employer should be obliged to support a personal choice made by an employee?
Ah finally!! You acknowledged that men are part of this process!!
Again, this has been discussed - it's the same reasons the maternity leave should be avaio.be with the added benefit of potentially addressing the issue of sex discrimination! Winner!
