The employer gives a written response within 21 days that grants the request, sets out an agreed different change reached after discussion, or refuses it. The employer may refuse only if it has discussed the request with the employee, genuinely tried to reach agreement on changes to accommodate the circumstances, has not reached agreement, has had regard to the consequences of refusal for the employee, and the refusal is on reasonable business grounds (for example too costly, no capacity to change others' arrangements, impractical to change others' arrangements or recruit, significant loss of efficiency or productivity, or significant negative impact on customer service). A refusal states the reasons and the particular business grounds and how they apply, sets out other changes the employer would make or says there are none, and explains the dispute rights in ss 65B and 65C.
