BHP Group Ltd (ASX: BHP) shares are sliding on Wednesday as investors react to reports of looming strike action at its Western Australian port operations.
At the time of writing, the BHP share price is down 3.16% to $57.01. By comparison, the S&P/ASX 200 Index (ASX: XJO) is down 0.5% to 8,759 points.
The fall comes after a strong run for the ASX mining stock. BHP shares are still up around 25% since the start of 2026 and almost 50% over the past year.
Here's what the report said.

Strike threat hits Port Hedland
According to The Australian, a coalition of unions is preparing to take strike action at BHP's port operations in Western Australia.
The action is expected to involve workers at Port Hedland, which plays a major role in the handling, blending, and loading of iron ore.
The unions reportedly said workers would walk off the job for 8 hours on 16 July.
While that may not sound huge, the site is particularly important. Port Hedland is one of the world's biggest bulk export ports and a key part of BHP's iron ore business.
Reports say the strike would involve 236 of about 450 employees working across BHP's port operations.
The dispute appears to centre on pay, conditions, career progression, and enforceable terms for port workers.
Why this could hurt BHP
BHP has previously warned that a shutdown at Port Hedland could cost the company around US$90 million, or $129 million, a day.
But the real risk is whether this could potentially turn into a longer standoff between BHP and the unions.
And the timing does not help either.
BHP shares have had a superb run over the past year, helped by stronger iron ore prices and better appetite for large miners.
With the stock still up almost 50% over that period, some investors may have been happy to take a bit of profit today.
The next date to watch
The planned walkout is set for 16 July, which gives BHP and the unions a short window to reach a deal.
If an agreement is reached before then, today's fall may not amount to much more than a pause after a solid run.
But if the strike goes ahead, attention may quickly turn to whether more stoppages could follow.
Iron ore remains the main driver of BHP's earnings, and Port Hedland is an important part of getting those tonnes out of Western Australia.
For now, investors seem to be taking some risk off the table while they wait to see whether the strike goes ahead.
