Hello {formtext: name=name of boss or manager; cols=5},
I am emailing you because I would like to request unpaid time off for {formtext: name=dates}. I ask because during this time I am {formtext: name=doing/going} {formtext: name=activity/location}. I understand that being gone for this time would make things harder for {formtext: name=staff/coworkers}, but I will make sure to get caught up on my work and even work ahead if possible. I feel that a short break would be good for me at this time and help me be more productive once I return. If you'd like to meet to discuss this further, feel free to email me or call at {formtext: name=phone number}. I appreciate your time and understanding. I look forward to hearing from you.
Sincerely,
{formtext: name=your name}
