MONTREAL, April 7 (Reuters) - Canadian Airbus A220 assembly workers on Sunday rejected a second company offer, raising concerns over production of the money-losing jet.

The contract talks with the estimated 1,300 workers come as Airbus is trying to grow production of its smallest commercial jet, as it rides a broader wave of orders from airlines coping with a rebound in travel demand from the COVID-19 pandemic.
