A new mum and high-earning mining data specialist who begged for a six-month extension to her parental leave due to a lack of childcare has lost a landmark battle against her employer.
Jessica Donnelly, a Brisbane-based data reporting specialist for Whitehaven Coal Mining Limited earning around $187,000 a year, took her employer to the Fair Work Commission after they rejected her plea for more time at home with her baby.
Ms Donnelly began her 12-month parental leave in August 2025 and was due to return to work on August 3, 2026.
In February 2026, she officially requested a further six months of unpaid leave, asking to push her return date to February 3, 2027.
However, Whitehaven Coal, a $6.6 billion company with operations across NSW and Queensland, refused the request just ten days later, sparking a bitter dispute.
The dispute culminated in a rare and “novel” Fair Work Commission arbitration regarding the extension of unpaid parental leave.
The Commission heard Ms Donnelly was desperately struggling to secure a five-day daycare spot.
She had meticulously researched local childcare providers but could only secure three days of care a week for her daughter.
She noted that a fourth day would finally open up after her child’s first birthday on September 9, 2026.
Meanwhile, Whitehaven Coal painted a dire picture of a workplace on its knees without her. The company argued Ms Donnelly had “bespoke knowledge and experience” using a highly specialised mining software called Corvus, making her nearly impossible to replace. Management revealed her data analytics team had seen its workload almost triple after taking on operations for four new NSW mines.
Colleagues were working 10 to 12-hour days and weekends just to cover her absence, leading to severe management concerns about psychological risks, high stress, and burnout among the remaining staff.
The company also estimated that bringing in an external contractor for the six months would cost between $182,500 and $202,000 plus GST, and noted that any temporary worker would require at least a 12-week onboarding period just to become useful.
In her submissions to the tribunal, Ms Donnelly said Whitehaven was a “large, sophisticated business that is more than capable of replacing a worker for a further period of six months”.
She said her employer had failed to prove the increased workload on her team could only be remedied by her return to work.
She also alleged Whitehaven was “dismissive” of her struggle to find adequate childcare. She said that when she raised the matter, she flagged she had inspected multiple centres and had put her child on a waiting list before birth.
In a first-of-its-kind decision on an unpaid parental leave extension, Commissioner Paula Spencer ultimately sided with the coal mining giant.
The crux of the legal battle came down to a debate over how unpaid parental leave is actually calculated.
Under Australian law, workers are legally entitled to 12 months of unpaid parental leave. Because Ms Donnelly received six months of paid leave under Whitehaven’s corporate policy followed by a six-month unpaid block, she argued that her 12-month unpaid statutory entitlement should not start until her paid company leave had ended.
If this interpretation was accepted by the Commission, it would mean she still had six months of her original unpaid leave allowance left to use.
That, in turn, would have allowed her to demand the extra time off as a guaranteed workplace right, rather than having to beg the company for an extension.
However, Commissioner Paula Spencer found paid and unpaid leave can run “concurrently” as a single block.
“Section 79b of the (Fair Work) Act sets out that unpaid parental leave is not extended by paid leave or keeping in touch days,” she said.
“It explicitly states that if during a period of unpaid parental leave, that an employee takes paid leave or performs work on a keeping in touch day, that this leave or work does not extend the period of unpaid parental leave.”
The Commissioner ruled that Whitehaven Coal had properly established “reasonable business grounds” to deny the mother’s extension request.
It found that the employer genuinely needed Ms Donnelly back in the office to alleviate the immense workload on her highly specialised team, which was receiving more work tickets than it could actually close.
“(Whitehaven) requires (Ms Donnelly) to return to her work to alleviate the pressure (the data team is) facing and that there is no viable alternative bar (her) return to work to accommodate the range of matters referred to in their reasonable business grounds for the refusal,” she said.
“I have found that (Whitehaven’s) rejection of (Ms Donnelly’s) request to extend her unpaid parental leave was refused on reasonable business grounds.”
However, noting the extreme difficulty of securing childcare and the need for fairness between both parties, Commissioner Spencer struck a last-minute compromise.
Acknowledging that Ms Donnelly would gain an extra day of childcare once her baby turned one, the Commission ordered a very brief extension of her leave until September 11, 2026.
Ms Donnelly is now legally mandated to return to work on September 14, 2026, bringing an end to the fierce workplace dispute.
The Commission noted that this short grace period would give the mother time to finalise her childcare arrangements while allowing the company to prepare for her extensive retraining schedule.
