Dear …
 RE:  __(Name of Employee)__ - Transfer Recommendation 
I am writing this on behalf of. __(Name)__, one of the employees I supervise in the __(name of area/department)__.  Over the past __(# weeks/months/etc.)__, __(Name)__ has been given responsibility of taking on only light duties because __(he/she)__ is no longer physically able to handle the heavy work load.  Unfortunately, __(his/her)__ __(name of illness)__ restricts __(her/his)__ movement, which has left __(him/her)__ unable to fulfill the job requirements of __(briefly describe the type of work he/she cannot do — i.e. lifting of heavy boxes)__.  
__(Name)__ has always been a loyal employee with a good attitude and good work ethics.  Therefore, I wish to recommend that __(he/she)__ be transferred to another department where __(he/she)__ will no longer be required to take on this type of heavy labor.  I am not suggesting a demotion for __(him/her)__, rather a lateral move to a different, less physically demanding, position.  __(Name)__ has proven __(his/her)__ worth as an asset to this organization and I believe that __(he/she)__ deserves an opportunity to continue working for us with dignity. Thank you kindly for your consideration of this request.  I remain hopeful that such a transfer is possible and  I’m  looking forward to hearing from you soon. 
Sincerely,
