Hereyougo - instead of criticising the Op, why not read up on legislation.
It has absolutely nothing to do with her Contract, it is an employment right. Completely separate to any other leave. They cannot refuse it, they can only change the time. Within 7 days, in writing. They didnt do that. An employment lawyer would pull them to bits if she was to go to a tribunal.
As for providing cover, so are you saying Op can never have any parental or dependant leave ? What if her DD became very ill and needed a major Op, or was in hospital for a long time? She would have to go to work because no cover could be provided? Bullshit. I suspect, like roundabout, you just think she is being cheeky because she is going on holiday. You would think differently if it was a hospital stay. The reason for the leave is nothing to do with employer, she has asked, they can only refuse with a good reason.
I had to take unpaid leave when my DD had open heart surgery as a toddler. Can't remember whether it was officially parental leave, we knew it was coming but didn't get much notice in end. Thank god I wasn't seen as cheeky by my employer for wanting a few weeks unpaid leave to be in hospital with her and then to look after her until she could go back to nursery. Thank god I didnt have to contemplate resigning, just so that I could be with my DD when she needed me most. I am part time too!
The whole point of the legislation is to ensure that employers like Ops cannot just give a blanket No without any thought. I suspect in this case though it is the managers who have no idea on legislation and that HR will know the law and take a different view.
