Can an employer change an employee's work roster?

Being penalised for unpredictability is not necessarily adverse action.

CFMEU v Endeavour Coal Pty Ltd [2015] FCAFC 76 demonstrates that it is not unlawful for an employer to change an employee’s work roster where there is unpredictability in the employee maintaining the original roster even where that unpredictability arises from the employee taking carer’s or annual leave.
