In 2020, Lisa was earning roughly $110,000 a year in a remote, corporate manufacturing role when she received an offer for a hybrid job that paid about $150,000. After talking it over with her husband, she landed on an unconventional solution: Take the new job - and keep the old one, too. For 18 months, Lisa secretly worked two full-time roles, earning roughly $250,000 in 2021 and averaging 40 to 50 hours a week across both jobs.
