I would guess that it depends on your manager and what kind of person he or she is. Sometimes it is best to apply for FMLA protection first through the HR dept - if the place where you are employed has an HR dept. You can apply for intermitten leave - which means that you can take an hour here or there as you need to without being punished for missing time. You do have to use up your vacation/sick time doing that and when your vaction/sick time is all gone then the time out is without pay. Which I know can be very difficult, I mean who can go without part of their salary ?? But sometimes part of a job is better than losing all of the job.

If your immediate manager is reasonable, they will completely understand the FMLA situation and will probably be as supportive as possible.

Good luck to you.
