I know people at work that spend so much time trying to convince other co-workers, and management about all the problems they have doing there job that they don't have time to do it. It doesn't make any sense to operate this way. You are responsible for how you operate in life. Looking in the mirror is the best way to get to the root of the problem. It's you.
You are the one who can fix any problem you have in the workplace. Why? Because you created it. If management is upset with you they have a reason. I've never met a great worker who believes management is out to get them. If it seems that way because you're probably not doing your job. There are bad managers who have agendas, create conflicts, and lie. I understand that.
When you have "leadership" like this you have to find the solution. Looking for the solution or expecting help from a manager like this will never happen. You have to figure it out. Back up your work with photos, emails, or any other proof. I've had these conversations with people and the excuse is usually "I shouldn't have to do all that" and that's true. There are a lot of things in life you shouldn't have to do. Unfortunately that isn't the way it works.
The person that says that, isn't doing the work. That's why they won't do it. If you have problems at work you have to let them see. What will happen is when you work harder the people take notice. I've experienced even the people who were against you before now become your supporters. Hard work fixes problems. It's cliche' but it's true.
When you stop making excuses, and trying to convince everyone about your problems it's amazing what the results will be. You will see a stark contrast to how management treats you. When you understand that your manager isn't paid to be your friend.
They get paid to encourage you to produce. Period. Whatever that encouragement entails.
