An estimated 25.5 million Americans face challenges like these every day as they struggle to balance work responsibilities with caring for a relative aged 50 or older. Not surprisingly, they wind up distracted, emotionally drained and physically exhausted.

The good news is that many employers are sympathetic to these demands. Some companies have programs to help caregivers find community services, counseling, respite care, legal and financial assistance, and caregiver support groups. Others have begun offering caregiving leave and flexible work arrangements.

Of course, every caregiver's job is different, and even within the same company, different managers may be more or less supportive. These tips will help you manage your dual roles.

Learn about company policies. Talk to your human resources department or read your employee handbook to ascertain your company's policy regarding caregivers. Find out about any benefits your company may offer, such as an employee assistance program.

Know your rights. Ask your human resources department for information about the Family and Medical Leave Act. Have them send a copy to your supervisor as well, if appropriate. Under the FMLA, eligible workers are entitled to 12 weeks per year of unpaid leave for family caregiving, without the loss of job security or health benefits.

Talk to your manager. Be upfront about your role as a caregiver and the demands that it puts on you. It's better that she or he hear from you why you're coming in late or seem preoccupied. Spell out the concrete steps you can take to juggle your competing demands. For instance, say, "I just found out my mother needs weekly physical therapy on Wednesday afternoons. While I'm looking for other arrangements, I propose that I work late on Tuesdays." Chances are your company will reward your honesty and sense of responsibility toward both your family and your job.
