Mediation between a Waikato dairy company and the Dairy Workers Union is set to continue this week.
Their dispute is over a collective agreement for union members at the Waharoa factory operated by Open Country Dairy.
A strike notice has been issued by the union, followed by a six-week lockout by the dairy company.
That lockout has since been ruled illegal by the employment court, but union members have been unable to return as the company says it's investigating the possibility of environmental sabotage at the factory.
It's also proposing to restructure the shift-based system that personnel are employed under.
Mediation began last week and is set down for a further two days this week.
