Obviously without more detail its hard to say for sure...
BUT - whenever my staff say to me that I dont get something about their job or the business, invariably its because they're looking at it from their perspective, not mine. If they try and convince me to do something at work, they're trying to do so for reasons that are pertinent to them, not to me.
Each staff member, particularly with different seniorities, will always have different perspectives on what needs doing.
However if you want to convince someone of something - you have to convince them from their point of view, not yours.
