Victorian police officers have won a ground-breaking "right to disconnect" clause in their enterprise deal that relieves them of a duty to respond to emails or telephone calls outside their effective working hours.

Clause 59 of (VICTORIA POLICE (POLICE OFFICERS, PROTECTIVE SERVICES OFFICERS, POLICE RESERVISTS AND POLICE RECRUITS) ENTERPRISE AGREEMENT 2019) says that supervisors and managers must respect officers' periods of leave and rest days.

It says that - other than in emergencies or genuine welfare matters - police between the rank of constable and senior sergeant and protective service officers must not be contacted outside working hours unless the employee is in receipt of an "availability allowance".

Theallowance is payable for each hour an officer is available, other than when they are rostered for work or expressly directed to be available.

For these officers, the availability allowance will be $7.15 an hour on non-rest days and $14.33 an hour on rest days, from July 1 this year.

More senior officers - superintendents, commanders and inspectors - already receive anannual contactability allowance

Superintendents or commanders who are not directed to be available for work will not be required to work but must remain contactable, while inspectors who are required to resume work will receive an availability allowance
