THE SHIFTING WORKFORCE: HOW A CAREER BREAK CAN MEAN MORE THAN JUST TIME OFF

Did you know that almost 25% of caregivers are under the age of 35?1 As Millennials near the age of 40 and Gen Z’ers find themselves a couple years post-college, many are navigating the demands of both careers and caregiving. And in the process, they’re challenging career norms and redefining the rules on their own terms.

The behaviors and choices of Millennials are profoundly disrupting business and society alike. In Deloitte’s 2019 Millennials survey, they found that 49% would, if they had a choice, quit their current jobs in the next two years.2 This constitutes a major challenge for companies seeking a stable workforce, and a total shift in workforce mindset.

So, if almost half of all Millennials are willing to quit their full-time jobs, what are they considering instead?

According to the study, 84% of Millennials wouldn’t hesitate to jump into freelance or contract work. Those who would consider joining the gig economy cite the chance to earn more money (58%), work the hours they want (41%) or achieve a better work/life balance (37%).3

Many Millennials are taking things a step further, scrapping the idea of a traditional career altogether. Instead, they’re creating careers on their own terms. Examples include deferring a future in civil engineering for a life on the Alaskan frontier as a sled dog musher or retiring at age 38 because of extreme savings. This is part of a new trend called “Millennial burn-out,” a generational shift that has many people making life choices that prioritize fulfilling experiences and relationships over careers.4

With 40% of women taking a break from full-time employment at some point during their career,5 it looks like Millennial women are redefining what that break could mean. The long-term impact of this attitude shift is still unknown but will certainly be seen for decades to come, especially as the percentage of millennial caregivers continues to rise.

If you’re a caregiver, experiencing millennial burn-out and think an alternative career path might be for you, it’s important that you start thinking through your goals and priorities. And then talk with people you trust – like your spouse, family members and even a financial professional. Having a clear plan in place – that balances life, career and financial goals – can make all the difference. Just ask the woman that retired at 38 because of her frugal savings strategies.6

The Way We Do Business

As we work together, we view ourselves as your allies and partners. Our ongoing discussions form the basis of our relationship.
    Icon Image
    Step I
    Our initial conversations will help us understand the most defining insights about you – from the values that inspire you to your most important proprieties and concerns. That’s how we learn what you would like your wealth to accomplish now and over time.
    Icon Image
    Step II
    Our next step will be to review all assets and liabilities on your personal balance sheet so we can assess where you stand today. We will also talk about risk – how much is too much when it comes to your strategy? It’s important we understand your comfort level with risk, so that we can develop an appropriate plan, tailored for your future.
    Icon Image
    Step III
    After closely analyzing this information, we gladly collaborate with your other trusted advisors to ensure that our collective guidance is consistent and aligned. Once our assessment is complete, we will provide you with a recommended strategy tailored to your needs and goals, investing time to educate you about the details of your plan.
    Icon Image
    Step IV
    Our final step in the process is implementing the strategy you’ve agreed to – putting to work for you the full range of global resources Morgan Stanley has to offer.

    Our work as wealth advisors is never quite done. The key to maintaining the success of your financial plan over time is reviewing that plan and having the foresight and flexibility to adapt to changes and new developments in your life. By working closely with you at every stage we can be proactive in making adjustments and rebalancing our investment portfolio to ensure that you consistently stay on track to achieve your goals.

About Kathryn Castelli

Starting with her first Wall Street firm in 1994, through Morgan Stanley today, Kathryn has always sown the seeds of a solid, long-standing financial planning practice, now celebrating client and extended family relationships nurtured over a quarter-century. Kathryn’s consultative process begins with an in-depth discussion of current finances and future objectives. Her focus on retirement planning goes well beyond providing investment advice, often uncovering areas overlooked, which can impact the ability to execute on what is planned. For Kathryn, maintaining the financial independence and lifestyle clients have worked their whole lives to achieve is the primary focus. She values the unique goals, values and circumstances of each relationship that determine the strategies developed on their behalf.

To Kathryn, her career as an advisor means investing time and energy into her clients, as well as herself, the financial services industry, and the community. Before becoming an advisor, Kathryn held full-time Legal and Compliance roles while completing her Business Management degree at Fordham University, graduating with honors. She finished top ten in advisor training, the only female out of 100 new advisors, and spent almost a decade at Merrill Lynch before being recruited to her current home at Morgan Stanley in 2011. Kathryn holds Certified Investment Management Analyst (CIMA®) and Chartered Retirement Planning Counselor (CRPC®) designations, both of which require ongoing education and adherence to the highest industry and ethical standards.

Kathryn has been happily married for 27 years and raised 3 children during her career. She regularly volunteers for the SIFMA Foundation, teaching and judging The Stock Market Game, and has held various roles on committees and boards supporting organizations that impact her children, their friends, and their community in Bayside, Queens. A Bronx native, she proudly provides ongoing mentorship to students in Fordham University’s business school through their Alumni Mentorship Network.
