In some cultures you only give your opinion or make suggestions when invited. Some migrants can be unsure when and how it is appropriate to give opinions in the New Zealand workplace. Three farm workers are meeting to work out the best order for completing the different components of a task. New migrant Lita has the results of a trial run showing what worked best.
Lita was right to not interrupt when Helen and Dave were trying to make a decision. They will ask if they want her input.
Lita has the trial results and knows what worked best. If Helen's suggestion was the best one Lita could say "You should put it at the end."
Lita has the trial results and should contribute what she knows. If Helen's suggestion was the best one Lita could say, "It might be a good idea to put it at the end. It worked well there in the trial run."
Lita needs to contribute to the discussion. She has the trial results which can help them reach an informed decision.
This is a possibility but 'you should' is very direct and strong. New Zealanders tend to soften their language when they make suggestions or give advice. She could soften her suggestion by saying something like "the results show that putting it at the end works best"
This would be a good way of expressing her opinion. She has softened her suggestion by saying "It might be a good idea." She also further softens her suggestion by referring to the trial. New Zealanders tend to soften their language when they make suggestions or give advice, so this would be appropriate.
