Everything you need to know about OHS Compliance
When healthcare staff walk off the job, your focus lands on patient safety and coverage. However, your occupational health and safety (OHS) obligations for the workers who stay and those who step in do not pause during a labour dispute. Fatigue, unfamiliar units and heightened tension on the picket line all raise real risk. Here is what stays on your plate once the strike begins.
Your OHS duty doesn’t pause when the picket line goes up
A strike changes your staffing plan, not your legal footing. Under the Canada Labour Code and most provincial OHS Acts, an employer’s general duty clause requires you to protect every worker on-site, regardless of how long they’ve been working there. The Canadian Centre for Occupational Health and Safety (CCOHS) clarifies that the duty extends to every worker on the premises, whether they have been there a decade or a single shift. That duty holds through a labour dispute and a staffing gap.
The hidden risk in leaning on replacement staff
Replacement staffing solves a coverage problem and creates a new one. A nurse who normally works telemetry gets pulled onto an unfamiliar medical-surgical floor, receives a fifteen-minute orientation and picks up a full patient load by the second shift. Multiply that across a hospital running on temporary staff for a week or more, and small gaps in unit knowledge start to compound.
One study found that hospitals leaning heavily on agency staff and overtime saw higher rates of pressure ulcers once staffing crossed a safe threshold. The fix lies in proactive partnership, not just last-minute orientation. Working with a dedicated healthcare staffing partner ensures that replacement staff arrive not only fully credentialed, but with specialties matched to your open units. The right partner works with you to streamline unit-specific onboarding before a crisis, turning a potential liability into a safe, integrated part of the team.
What a major labour disruption can teach you
When the Minnesota Nurses Association walked out in 2022, the disruption affected 16 hospitals across Minnesota over three days. Hospital administrators brought in contract nurses to keep units running, and the sheer scale forced a level of coordination most facilities had never planned for, including credentialing hundreds of temporary staff, matching them to units by specialty and briefing them on unit-specific protocols within hours instead of weeks.
That kind of pressure test is instructive even outside the country where it happened. If your contingency plan can say who orients replacement staff and how fast before a strike ever starts, you are ahead of most facilities that learn this the hard way.
Keeping picket lines and patient floors psychologically safe
A strike raises psychological safety risk on both sides of the picket line. Tension between striking staff and replacement workers can escalate fast, and remaining employees often absorb extra shifts, extra scrutiny and public criticism at the same time. Canada’s federal Labour Program tracks this pattern, and employers reported over 7,000 incidents of harassment and violence in 2023 across federally regulated industries, a signal that regulators take this exposure seriously, even where oversight is provincial rather than federal.
Build a security plan for entrances and parking, brief security staff before the picket line forms and give managers a clear script for handling confrontations. Waiting for an incident to happen is already too late.
- Review your contingency plan for dedicated OHS chapters and replacement staff.
- Identify key safety roles on each shift.
- Prepare orientation packs for each unit with floor plans, emergency contacts, unit-specific hazards and more.
- Draft communication scripts for managers to help them handle picket lines.
- Audit IT access that is available only during a person’s shift.
Strengthening OHS readiness during healthcare strikes
A strike tests everything about how your hospital runs, including how seriously you take worker safety when the org chart gets rearranged overnight. Orient replacement staff properly, plan for tension on the picket line and remember your OHS duty follows every worker on shift, not just the ones who were there before the strike started. Build that plan before the picket signs go up.
