Case C-834/19, Part time work, fixed-term work

Does the national practice whereby honorary district court judges who work as described [in the order for reference] (as in AV’s case) are excluded from the concept of ‘part-time worker’, as referred to in Clause 2 of the Framework Agreement annexed to Directive 1997/81/EC, and from the concept of ‘fixed-term worker’, as referred to in Clause 2 of the Framework Agreement annexed to Directive 1999/70/EC, constitute an obstacle to the effectiveness of Directives 1997/81/EC and 1999/70/EC?
