Well yes and no. It all depends on what is being requested and the reasons why. Fed stats show that about 41% of Americans have non-traditional work schedules. Courts more and more realize this and want to find a way to make it work. Its not always viewed as whats best for the parents work schedule but still whats best for the child(ren). Where OP has enough notice of his schedule, that may be enough however where OP can try to get a set schedule on the days he has visits, that would work better.Regarding filing for a modification and requesting flexibility, that request could backfire, as someone else here said. An order that allowed you to request changes to the visitation schedule based on your work schedule that week would necessarily allow her flexibility as well, because the court probably won't make an order stating that you may take the kids whenever is best for you. Instead, an order allowing flexibility would probably allow for adjustments based on mutual agreement. With her apparent desire to make things difficult and cause conflict, that would just give her more room to cause problems by not agreeing to your requests whether the adjustments work for her or not.
It seems that in order to simplify things your best bet would be to file for a modification to allow you to designate others to pick up and drop off. That way, you will not necessarily need to be there for exchanges. As others have said, she will not work with you to change days on an every other week basis, so that is not something I would waste my time on. Seeing as how you are doing this pro se, it would be best to simply modify or clarify the pick up and drop off issue.We live about 20min apart, and the school is 15min from me. My schedule is not on a regular rotation, there could be different days off each week and different shifts as well. I know my schedule about two weeks out, and would be able to communicate that asap. My ex is a teacher, so her schedule is set and would be a little easier to change days than with mine.
If I had to set a specific day, then I would run the risk of working on that day from time to time and creating issues with the pick up and drop off. However, if I could have my current wife pick up the kids if the schedule conflicts I would have no problem getting them to school the next day.
I just can't think of anything else that would always work out. I am going to talk to my boss tomorrow to see if I can get a set week day off, so hopefully that goes well.
