I am all in favour of SRO I have to say, as I feel it is better for the children to have two parents considered equal in the eyes of the law and it allows both parents to parent effectively without eiterh feeling second class or being dennied info about their child from schools, doctors etc.
However a SRO does NOT mean equal time and does not have to mean equal time either.
I agree with others here that if he is going to have them an additional overnight, and goes to court over this, I would really question his motives given that he already has a very decent amount of time with them and doesn't seem to be putting the children's needs first with this suggestion.
You haven't said how old your children are and thus it's hard to know when their bedtime would be or what afterschool care they would need (homework, activities etc).
But picking them up at 6.30 from you means that you still have had to collect them from school. You will do homework with them, deal with any afterschool clubs or visits to/from friends, and in all likelyhood give them their dinner and be the one sorting out their bags (lunch boxes, PE kit, letters home etc).
The children also may be excited about going to see dad and therefore are less likely to settle to homework etc too and might even miss out on some clubs that might be later in the evening such as cubs/scouts/brownies.
So what is it that he is actually going to get in quality of time both for himself and the children by picking them up from you at 6.30?
All that will happen is they will wash and change at his, go to bed and be given breakast and a lift to school in the morning. Which seems to all intents and purposes as if he is simply doing this to up his overnights.
You can not choose to work longer hours with this arrangement, you still have the majority of the costs associated with this day, and the quality of time he will spend with the children is poor imo as is the amount of parenting time he will actually achieve with this arrangement.
Midweek contact is usually considered a good thing to allow the parent to have more contact with school and to have real, everyday parenting time to be able with homework, afterschool clubs etc. He is not going to be getting any of these things so how exactly does he see it benefiting the children to have this extra time?
Would he accomodate you by collecting the children from school and taking care of them till you could come and get them after work at 6.30? Perhaps you should ask him! If he is agreeable maybe he can do that on the monday he drops the children at school, or the friday that he doesn't have them overnight, so you can have more flexibility with your own working arrangements.
He can't have it all his own way I'm afraid. I don't know how things have been in court for you both, whether you have been able to agree things by and large or if it has been a big battle. Do you have the same judge each time? Is the judge not bored by now and telling him to go to mediation to sort this out? Has your ex suggested mediation as a way to move forward on these things rather than going to court each time? If not maybe you could suggest it as it seems a lot of stress and hassle to keep putting you all through.
As I said I'm in favour of SRO, but Shared Residency doesn't automatically equate to equal time. Contact should be about what is best for the children, not what dad (or mum) wants. He needs to show how this will be of benefit to everyone, and if he can't then perhaps it is just money motivated.
Hopefully I answered your question regarding that side of it in my last post to this thread
Take care
