16 hours of work is the max

With a fluctuating number of Registered Nurses employed in the workforce, staff at some worksites are asked to work more than a double shift, which equals more than 15.5 consecutive hours. UNA’s Provincial Collective Agreement prohibits this unsafe practice: 8.03 No Employee shall be requested or permitted to work more than a total of 16 hours (inclusive of regular and overtime hours) in a 24 hour period beginning at the first hour the Employee reports to work. Working extra hours can have professional conduct implications. The Practice Standards for Regulated Members, published by the College and Association of Registered Nurses of Alberta, states: 5.9 The registered nurse ensures their fitness to practice. Fitness to practice means that the registered nurse restricts or accommodates practice if he/she cannot safely perform essential functions of the nursing role due to mental or physical disabilities.
