Last week Joseph, a nurse at Perth Hospital, refused to bathe patients twice a day in accordance with a new direction from his employer. He told his supervisor that he was only willing to bathe them once a day, which was all that had been required in the past.

Joseph's supervisor warned him on Monday morning that he would not be paid for any work he performed unless he complied with this new direction to bathe patients twice a day.

However, Joseph attended work every day that week and performed his usual tasks. He was even complemented by his supervisor on his hard work that week. Despite this, Joseph did not comply with the direction to bathe his patients twice a day, and instead avoided talking about it with his supervisor.

Using the IRAC method, advise Perth Hospital whether they are entitled to withhold payment from Joseph for failing to follow the direction? You must refer to both legislation and case law where appropriate.
