The opposite of being responsible is to shrug, “What can you do.” Change in a company can only start when someone owns responsibility for the influence they have on their coworkers and workplace.
Getting change to happen at a company means starting with someone who feels responsible that what is happening at the company is “theirs” in some way, and helping them with what they want to happen.
They need to want something to be different. Help them figure out what they want to be different. Show them what they’re missing, or get them to tell you.
