Outsourcing the work doesn't outsource the risk
Contractor Safety Accountability
A contractor gets injured on your premises. Whose incident is it?
Most employers assume the answer is obvious: the contractor's own company handles it, because that's who employs them. But South African law doesn't let accountability move that cleanly. Under the Occupational Health and Safety Act, the person in control of a workplace carries duties toward everyone working in it, not just direct employees. That includes contractors, subcontractors and their staff.
This catches a lot of businesses off guard. Outsourcing the work doesn't outsource the risk.
Where the confusion starts
Companies often treat contractor safety as the contractor's problem to manage. A cleaning company brings its own equipment. A maintenance team brings its own training records. Surely that means the client site is covered.
Not quite. The OHS Act requires the host employer to take reasonably practicable steps to protect anyone on their premises, including people who don't appear on their own payroll. If a subcontractor's employee is injured because of a hazard the host site failed to identify or control, the host can carry liability alongside or instead of the contractor.
This gets more layered when there's a chain involved. A main contractor hires a subcontractor, who brings in temporary labour. Each link in that chain has some responsibility, and when something goes wrong, all of them can end up under scrutiny.
What accountability actually looks like
A few practical things tend to separate businesses that handle this well from those that get caught short:
Written agreements that spell out who is responsible for what, before work begins, not after an incident
Site inductions for every contractor and subcontractor employee, not just the company they represent
Proof of competency and training kept on file, not just assumed because a service provider says so
Ongoing site monitoring, because a contract clause doesn't prevent a hazard on its own
None of this is about distrust. It's about making sure the paper trail matches the reality of who is actually on site and what they're exposed to.
The COIDA angle
Compensation claims add another layer. Under COIDA, an injured worker's claim generally follows their actual employer, but disputes over who was responsible for the conditions that caused the injury can still land on the host company's desk, particularly where negligence or a failure to maintain a safe environment is alleged. Getting the contractual and safety documentation right upfront makes these situations far easier to resolve, and far less costly.
A shift worth making
The safest approach treats every contractor on site as part of the safety system, not a separate one running alongside it. That means the same induction standards, the same reporting culture and the same expectation that hazards get flagged regardless of who's technically on the clock.
It also means asking a harder question before signing any contractor on: not just "can they do the work," but "can we prove, if we ever needed to, that we managed this properly."
Because when something goes wrong on your site, "it wasn't our employee" has never been the full answer.
