Should I refuse a task from my boss?

I think it would be a good idea for your to share your concerns about the business plan directly with your boss. However, do not say that you "think it's naive and paranoid!" Those are purely emotional responses and they will carry no weight in a business setting. Find concrete examples of how this plan will be detrimental to your company and ask your boss to consider them. If he/she refuses, then you can certainly ask not to be assigned to work with your old colleague - and your boss might not be confident in placing you in that situation anyway, once your feelings about the project are known. Ultimately, if you are still assigned to work with them, you don't have much choice about doing it -- unless you don't value your job that much or your working relationship with your boss.

If I were in your shoes I'd accept the task, considering your boss is also your friend, and the type of task your boss is assigning you. On a positive note, it seems challenging.

This sounds like a tricky situation. Does your boss know of your concerns? I don't think you can refuse this task without explaining why.

You can talk all your thinking of that thing to your boss but all because of work, not based on the private relation. I think your boos will have decision about it. In case, your boss still want you to work with them, you can refuse that task. I am sure that you boss will understand your decision.

you can talk to her and discuss anything you like in a good way, i mean you should not just follow what he or she says, they are bosses yes but they are human some of them are feeling but some are not, so the really one who should decide to say your feelings or no is you, you know her pesronality better, does she accept aruguaing or talking about orders or she is just bossy type of bosses, and is the task really worht it or not, its really up to you only to see and find out how and where or how to do that so

Being honest with your boss about issues at work is usually the best policy. When you feel in your gut that something won’t work, it is better to respectfully explain to your boss why you think it won’t work. He/ she will be grateful that you saved them from making a blunder that would have cost them. However, if they insist, then go ahead and do as they ask.

i think what you can do is to try to let him know you are still doing things at the time he or she is asking you to do something. he/she should understand what you need to prioritize at work, right?

good day tkonlinevn, with reference to your main topic, if i will be place in your situation, i will follow what's the boss instruction. since, i am working to the company where my boss is also engaged, so i will do whatever his instructions are. although, i don't feel comfortable to work on the team that handles the samples and plan, still, i will follow the instruction of my boss. thus on this part, i will just bear in mind that i am doing that task due to my boss instruction, hence in that way, i can somehow concentrate more rather than wander.

As long as this task really doesnt give you extra money, refuse it. you can be closer with your boss in many other ways :)
