There are a few things you need to know in relation to taking a leave of absence:
- When you request one, don't burn the bridges by saying that you are sick of the program. Cite personal issues instead: health, the need to take care of your family member, financial situation, etc.
- Make sure you know the rules associated with leave of absence. For example, you need to find out whether you will lose one year of funding if you decide to do so
- Don't come back into the program because you haven't succeeded in finding a decent non-academic job. If you think that hiding out from real life for a few more years will solve the problem of figuring out your place in life, you are up for some serious problems in the future. You should only return when you are hundred percent sure you want to continue your academic career
