When dealing with the death of a family member, you'll naturally want to know how much time you are allowed to take off from work to attend services and grieve your loss. This question is not one that can be addressed by looking into federal laws, as there is no federal legislation in the U.S. that mandates time off for bereavement leave.
Not a Federal Law Matter
While many companies do have policies allowing for bereavement leave, or personal time off (PTO) policies that allow employees to take time off with approval for any reason, there are no federal laws specific to bereavement. In fact, with the exception of the Family Medical Leave Act, which addresses time off due to serious illness and becoming a parent, there are no U.S. federal laws that dictate how - or even if - employers provide time off from work at all.
Determine Company Policy
Rather than searching for a federal law on this topic, what you should do is review your employee handbook to see if your company has a policy specific to bereavement. If so, the policy is likely to specify the particular relationships covered, and how much time is allowed. Typically, such policies are very limited, covering only parent, child or sibling and allowing between one and three days off, but specifics can vary significantly from one company to another. This type of leave may be with or without pay.
PTO or Vacation Alternative
If your company does not have a bereavement policy, or if there is a policy but it does not apply to your specific situation, the first thing you should do is identify whether you have any accrued time under your company's vacation or PTO policy. If so, follow your company's policy regarding requesting the time off that you need. When submitting your request, explain the circumstances as appropriate to help expedite approval.
If you don't have accrued time, either because you are not eligible for vacation or PTO or because you have used all your time, discuss the situation you are facing with your boss. He or she may be able to rearrange your work schedule or allow you to take leave without pay for an agreed upon period. While your employer does not have to approve such a request, you won't know unless you ask. Most employers are willing to work with good employees in such situations. Just be aware that they are not under federal legal obligation to do so.
