Building Your Locum Career: From Occasional Shifts to Full-Time Flexibility

South Africa loses close to 6,000 doctors and nurses per year to emigration and resignation. For those who stay - and for the growing number who choose flexibility over permanent employment - the locum model has never been more viable or more lucrative. 

Whether you are a GP supplementing your income with weekend shifts or a pharmacist considering a full transition to independent practice, the locum career path in South Africa now offers real professional and financial sustainability. Getting there requires a clear plan. 

Why the demand sustains a full-time career 

SA has 0.3 doctors per 1,000 people in the public sector - one-third of the WHO recommendation. Over 21,000 specialist medical posts are vacant across the nine provinces. The nursing sector faced a shortfall of between 26,000 and 62,000 nurses across all categories in 2019 - a gap the National Department of Health projects will grow to between 131,000 and 166,000 by 2030. 

These are not temporary gaps. They are structural, long-term, and growing. The South African locum staffing market was valued at USD 22.1 million in 2024 and is projected to grow at nearly 6% annually through to 2030. The professional with the right credentials and a reliable track record will find consistent demand throughout their career. 

The career trajectory: four stages 

Stage one - early career diversity. In your first two to three years of locum practice, prioritise clinical breadth over income optimisation. Take placements across settings - private practice, community clinics, corporate occupational health facilities, after-hours emergency centres. The clinicians who become most employable as locums are the ones who can operate effectively in unfamiliar environments without handholding. 

Stage two - supplementary income. For many healthcare professionals, the entry into locum work is through weekend and after-hours shifts alongside permanent employment. At standard GP locum rates of R475-R600 per hour, a single 12-hour Saturday shift can generate R5,700-R7,200 before tax. Two to three supplementary shifts per month materially changes your financial position. 

Stage three - building toward full-time flexibility. The transition to full-time locum work is most sustainable when you have an established network of facilities that know and request your profile, a solid SARS tax structure in place, and a financial buffer to manage months where shift volume dips.  

The transition to full-time locum work is most sustainable when you have an established network of facilities that know and request your profile, a solid SARS tax structure in place, and a financial buffer to manage months where shift volume dips. This is a gradual build rather than a fixed timeline - it depends on your specialty, how many facilities you register with, and how quickly you take on additional shifts. 

Stage four - senior independence. Experienced locum professionals at this stage control their own schedule with precision. They take only the specialties and settings that suit them, command premium rates, and often work across multiple provinces. Several of our most experienced candidates operate at this level until the year they choose to retire. 

What full-time locum life actually looks like day to day 

The primary trade-off is predictability. You do not receive a monthly salary on a fixed date. You do not accumulate annual leave. Sick days are unpaid. In exchange, you choose which days you work, in which discipline, at which facility, and in which region. Specialists working in high-demand areas such as ICU, oncology, and accident and emergency consistently report monthly earnings that exceed what they earned in permanent positions.

The financial structure you need before going full-time 

This is the section most locum guides leave out - and it matters enormously. 

Locum professionals are independent contractors under SA law. You are responsible for your own tax, and SARS will hold you to it. Register as a provisional taxpayer before you earn your first locum rand. You pay income tax in two annual instalments (31 August and end of February), calculated on estimated annual earnings. If your turnover exceeds R1 million, VAT registration is compulsory. 

The upside is significant: legitimate business expenses reduce your taxable income. These include professional registration fees, malpractice insurance premiums, CPD course costs, a portion of vehicle expenses (a logbook is required), medical equipment, professional subscriptions, and home office expenses if you administer your practice from home. Work with an accountant who understands healthcare contractors - they pay for themselves many times over. 

One important caveat: SARS may treat an independent contractor’s income as remuneration subject to PAYE if their services are performed mainly at a client’s premises and they are subject to that client’s control or supervision over how their duties are performed or their hours of work. Factors such as fixed hours, direct instruction and the degree of autonomy in how you work can all be relevant. Working across multiple facilities may help demonstrate independence, but your overall working arrangement remains important. Distribute your placements across facilities and you avoid this risk entirely. 

The platforms and support you should use 

Register with an agency that offers more than job matching. Ambition24hours Locums provides 24/7 operational support, handles HPCSA compliance verification, pays weekly, and has relationships with facilities across every province and major specialty. We are part of the A24 Group - a staffing organisation operating since 1996 across South Africa, the UK, the US, and Australia. The size of our network gives you access to opportunities that direct-to-facility approaches cannot match. Keep an eye on our latest news for updates on rates, compliance changes, and new facility partnerships. 

Maintain active CPD compliance throughout your career. HPCSA requires 30 CEUs per 12-month period. Locums who fall behind on CPD lose their competitive edge precisely when facility managers are making placement decisions. 

Frequently asked questions 

• Can I earn as much as a full-time employee as a locum?

  Yes, and often more. At specialist and GP rates, many experienced locums out-earn their permanently employed counterparts - particularly when working after-hours or weekend shifts. It's a completely reasonable question to ask before making a career change, and the numbers genuinely stack up in your favour.

• Do I get benefits as a locum?

  No - there's no employer-provided pension, medical aid, or paid leave, and that trade-off is worth thinking through carefully. You budget for these independently instead, which many professionals come to prefer once they've adjusted: you choose your own cover, your own provider, your own timing, rather than having it decided for you.

• How do I handle months with fewer shifts?

  This is one of the most common worries we hear from locums considering full-time work, and it's a fair one. The practical answer: maintain three to six months of operating expenses as a buffer, and diversify across multiple facilities and specialties to smooth out the quiet periods. Most locums find the dips become far less stressful once that buffer and network are in place. 

• What tax documents does Ambition24hours Locums provide?

  We provide full payment records and documentation to support your SARS submissions, so you're not left chasing paperwork at tax time.
