An employee recalled to work overtime after completing work must be paid a minimum of 4 hours work.  This will be 4 hours at overtime rates.  Where the actual overtime worked is less than 4 hours on such recall or on each of such recalls, such overtime worked is not regarded as overtime for the purpose of the 10 hour break under sub-clause 27.3 (sub-clause 27.4).

This call-back clause does not apply where it is customary for an employee to return to the workplace to perform a specific job outside ordinary working hours or where overtime is continuous (save for reasonable meal break) with the start or finish of ordinary hours (sub-clause 27.4(b)).
