“…OCB refers to actions that exceed what the employee is prescribed to do and become a set of desirable work behaviours (Torrente et al, 2012), since they contribute through a positive environment to develop in-role performance (Organ, 1988;Podsakoff et al, 2009;Chan et al, 2017). Some characteristics of OCB are that they support organisational environment (Mullins, 2010); are common to many jobs (Kim et al, 2013); are not prescribed (Organ, 1988;Van Dyne et al, 1994); and finally, the main drives to carry out such activities are the attitude and willingness of employees (Goodman and Svyantek, 1999).…”
