12 Jobs Or Career Options for Americans Seeking A Side Hustle Or Extra Income

In today’s high-cost economy, holding down a single job is no longer cutting it for millions of Americans. Recent data for Q4 2025 from Indeed Hiring Lab reveals that nearly 16% of active job seekers are already working multiple jobs while actively searching for another. Rather than taking on side hustles for fun, workers are increasingly doubling up in hourly, shift-based, and service roles to bridge income gaps.
Here are the top 12 jobs and career options Americans are turning to for extra income, identified directly from job-holder data and profile rankings:

According to research from Indeed Hiring Lab, delivery drivers tops the list of secondary roles held by multiple jobholders, capturing nearly 5% of active profile listings. The immense flexibility of app-based gig work and traditional courier shifts allows workers to easily slot delivery hours into gaps around primary work schedules, making driving one of the most accessible options for generating supplementary income.

Healthcare workers frequently double up within their specialized domain, with nursing assistant roles accounting for roughly 3.5% of multiple jobholder profiles. Data highlights that identical-title pairings are extremely common here, as certified nursing assistants leverage flexible shift structures, rotational schedules.

According to Q4 2025 data from Indeed Hiring Lab, hourly and shift-based roles dominate multiple job holding. Delivery drivers lead at nearly 5% of active profiles, followed by nursing assistants and customer service representatives at around 3.5% each. Servers, bartenders, sales associates, caregivers, drivers, security officers, and cashiers round out the top ranks, showing how workers leverage flexible schedules to stack income.

Representing around 3.5% of multi-job profiles, customer service representative positions offer crucial scheduling flexibility for those seeking additional streams of income. Many workers pair remote or shift-based support roles with another primary position. This job allows individuals to apply existing communication skills and product knowledge across different companies without requiring extensive retraining or specialized equipment.

Food preparation and service accounts for nearly 17% of active multi-job profiles, with server positions standing out as a primary choice.The data notes that hospitality roles feature variable hours and rotating shifts that fit seamlessly into evening or weekend schedules. Workers often combine serving duties with similar service roles to capture steady tips and immediate cash flow.

Bartending represents another major cornerstone of service-sector side hustles identified in the Indeed Hiring Lab study. Frequently paired with serving roles—making "bartender and server" the top cross-title combination—this option appeals to active job seekers because night, weekend, and event shifts rarely overlap with standard daytime working hours, allowing workers to efficiently stack income streams.

Caregivers account for approximately 2.2% to 2.3% of all active multiple jobholder profiles. Personal care and assistance roles rank prominently among hourly workers taking on extra jobs. Research demonstrates that caregivers often build income by accepting clients across different home health agencies or private arrangements. Flexible hours, part-time shifts, and non-overlapping schedules allow compassionate workers to deliver crucial support services while securing financial relief.

Security Officer accounts for approximately 1.8% to 1.9% of all active multiple jobholder profiles. Data from Indeed Hiring Lab shows security roles are popular due to overnight, weekend, and rotating shifts that accommodate second schedules. Workers rely on these steady, hourly positions to fill coverage gaps, ensuring predictable wages while balancing additional employment obligations.

Cashier accounts for approximately 1.9% of all active multiple jobholder profiles. Retail and service roles like cashiers are heavily represented among multi-job workers navigating tight personal budgets. Cashier roles offer accessible entry, straightforward duties, and flexible part-time hours. Many employees take on secondary cashier shifts at grocery stores or retail outlets during off-hours to offset rising living expenses and maintain financial stability.

Driving occupations overall represent a dominant segment in the secondary labour market. Truck drivers account for approximately 1.75% to 1.8%. Data indicates that commercial truck drivers frequently pick up secondary transport or haulage gigs. Given high demand and shift-based haul assignments, experienced drivers can easily monetise their licensed skills across separate fleets or regional logistics companies to supplement their main earnings.

Specialized healthcare professionals also frequently hold double roles to combat financial pressures. Indeed Hiring Lab finds that licensed practical nurses (LPNs) represent one of the most frequent identical-title job pairings.

Cleaning and maintenance roles consistently rank among the top service occupations for multiple jobholders. Housekeeper accounts for approximately 1.3% of all active multiple jobholder profiles. According to Indeed Hiring Lab, housekeeping positions enable workers to double up within the same skill set, taking on morning, evening, or weekend commercial and residential accounts. This structural independence helps job seekers tailor secondary work hours around primary jobs.

Administrative assistance is a top office-based option among active multiple jobholders. Findings from Indeed show administrative staff frequently leverage part-time office or virtual assistant roles alongside primary employment. Possessing transferable organisational and clerical skills, these workers secure extra income through flexible scheduling, remote options, and evening administrative support.
