Six Łódź threads, four people in India
A Łódź customer base is a mix: shoppers waiting on a parcel, a service centre's staff, a buyer at a factory, a founder. Try each strategy and see who ends up holding which conversation.
Round-robin is fair to agents and unfair to customers: the Polish-speaking shopper lands with whoever is next. Skills-based routing keeps her with Aditi; sticky routing keeps the ceramics buyer with Farah tomorrow too. Most teams answering Łódź combine the two.
The point for an Indian team is that Łódź threads arrive in a block, through the Indian afternoon and early evening. Settle the rule before the first broadcast, not after the first complaint.
