Packing up all the possessions of a family and saying goodbye to your current life can be trying. People relocate for all sorts of reasons, including the prospect of a higher-paying job. Relocating for work is frequently done and respected as a legitimate choice. Resigning from your current position can be difficult for you and the work environment due to job changes that must be made. It is important that you handle a resignation without offence or resentment.
Write the introduction first. Make it clear that the resignation is for the specific reason of relocation. Be very clear about the reason for the move as well. Tell the employer whether it is for a job, to be closer to family or some other reason. Abide by the general courtesy of giving the employer two weeks notice, or however long the employment contract states, if there is one. Keep the introduction short and to the point; the well-wishing comes later in the letter.
Emphasise the regret at leaving the position. Be sure to mention any specific incidents that you will remember favourably. Do not burn the bridge; it is very wise to keep it intact. No one knows when he might run into former coworkers. Talk about the opportunities the job afforded and how you will apply the lessons learnt in the future. Offer to help train a replacement worker. Mentioning anyone by name can be hazardous; several people in the office will likely see the letter.
Extend gratitude to the immediate supervisor and coworkers. Make sure that no one could perceive the closing as offensive in any way. It is very important to leave on a positive note. Be absolutely professional and diplomatic. Show gratitude for having worked there and the skills you learnt. Keep personal observations and notes out of the letter completely. Say nothing negative or disparaging about the company or any of the employees. This letter will likely be included in an employment file and may be shared with future employers.
