What about insurance... I originally said I would keep him on but now I am having second thoughts and want to take him off because I'm having to pay $240 per month.
Possible email:
"Hi WH,
I have decided it would be best to remove you from my health insurance. I plan to make the change effective for July 9, 2010 which will give you enough time to make arrangements on your end so you do not have to go without any coverage. If there is not open enrollment at your work you should be able to still get coverage due to a change in status. Please let me know if you have any questions. Thanks."
