Most acting appointments run between 2 weeks and 6 months. For appointments longer than 6 months, most workplaces will open a formal permanent recruitment process. Always include a clear review date.

Should acting roles get extra pay?

Extra pay is recommended for acting roles that include additional responsibilities or authority. For short appointments under 2 weeks, pay adjustment is not always required. Always state pay terms clearly in the letter.
