Sometimes, you need extra time away from work to take care of yourself or your loved ones. Lam gives you the time you need to accommodate these planned or unplanned situations—like bonding with a new addition to your family, recovering from an injury, caring for a relative, or serving in the military.

Types of leave

All regular U.S. employees working at least 20 hours per week are eligible for a leave of absence. During your leave, you may be eligible for job protection and for income replacement through your short-term disability insurance (STD or, in California, VDI). You also should be aware that different leaves impact your Lam benefits in different ways.

Following is an overview of each type of leave. Details are in Leave of Absence and Accommodation Practice [PDF] and the Workplace Accommodations Notice [PDF].

Maternity leave

Parental bonding leave

Medical leave

Family care leave

Military leave

How to request a leave of absence

Regular full- and part-time employees who are planning to take time off from work for more than seven calendar days and who will not be using paid time off (PTO) or other paid time must initiate a leave of absence.

If you plan to take a leave of absence, you should notify your supervisor at least one month prior to the leave (if foreseeable) or as soon as reasonably possible (when leave is not foreseeable). Lam will provide family or medical leave in accordance with state and federal laws in effect at the time the leave is granted. Military leave will be granted based on your service orders. Requests for a personal leave of absence must be approved by your supervisor or department manager before you can file a claim for the leave.
