Would like to keep this unbiased if possible.
Sarah and Ben have two children together and are separated. Ben is now married to Claire (B&C also now have young children of their own).
S&Bs children stay with B&C 2 nights one week and 3 the next currently. The week with 3 nights is over the weekend and the week with 2 is during the week.
Ben works, Claire is a SAHM and Sarah has been studying for the past number of years around her part time job.
Sarah has now qualified and is beginning a new job which will involve shift work meaning the her and Ben's children's normal contact schedule will need to change and follow Sarah's shift patterns rather than set days that they now have. This will inc upping contact to 3 nights every week whilst Sarah works. Ben is saying this is not possible as he's already arranged his work around the schedule they have had for years and cannot change this dependant on Sarah's shifts for that week. He has agreed to up contact to 3 nights per week but has said these must be set days.
Sarah has suggested Claire help if Ben is not around on one of the days, Claire has said no and agrees with Ben the contact schedule should remain the same as its what everyone has worked around for years Inc the children.
Who is being unreasonable?
Sarah for saying contact needs to follow her shifts instead of being set from now on and if Ben can't do that maybe Claire could help out. YANBU
Ben and Claire for insisting contact should follow the same schedule as normal and be set, not change week by week (although they do agree to up to 3 nights per week). YABU
