As on what reasons to point out, you have to take your personal objections aside and assess the client with a business perspective. If the client has dubious business practice for example, but your company will haveis already doing business with them, it is clear that they want to balance whether the potential incomestick with it for the company outweighs the potential for legal issuestime being. Between black and white there are a tone of gray spots to fall in, and I'm pretty sure this client is neither clean or evil only. Either way, you can express your concern, but the decision is not up to you unless you really are part of the upper management.
I would like to express my concern regards to working with "CLIENT". There have been past episodes where this type of <products/projects/business area> have been exposed to lawsuits with important losses for the companies involved. [Refer to any jurisprudence that might exist]
Furthermore, a few people in the company share my concerns and would not be comfortable working with this project.
While I acknowledge that working with "CLIENT" will provideprovides us with an important amount of income, I recommend that legal counselmy team is brought in and the consequences ofuncomfortable with working with this project are weighed in before making a decisionclient and we would prefer not to be involved with them.
Please have a thorough review on the client's history and this concerns. I am willing to offer support and information wherever needed.
First of all, thank you for raising your concerns about "CLIENT". I have definitely thought about it, and share (some/many) of your concerns. I have escalated this issue to "NAME OF THE COMPETENT PERSON", to make sure that the project is aligned with the values of our company.
Unfortunately, a decision has been made that we will go on with this project.
I have made my best effort, to the greatest level of my attributions in this company, to try and reassign you to another team, but unfortunately it is not possible because (understaffing / skillsets required / management refused / etc).
I understand that this is a great disappointment for you, and should you decide to work with us in this endeavour, I will strive to make as many accomodations as possible for you to be able to do your job.
Rest assured that this decision is a company decision made by "UPPER MANAGEMENT", and does not hold you, or anybody of our team, accountable for taking it. Legal counsel has been asked for and our company lawyer is working hard contract wise to ensure the project is properly insured for liability to the level of risk we will have to deal with.
Please let me know your comments about this, and feel free to speak me privately if you are more comfortable with it.
