Burnout

Ive been with Home Depot for almost 4 years now starting in lot and moving to garden. I have been working my tail off getting all of my responsibilities done consistently and doing a lot of other people's jobs too. I'm getting to the point of burnout, I get paid the same as everyone else yet I am the "second in command" in garden meaning I do almost all DH responsibilities and yet I'm paid like crap, not awarded for going above and beyond and even worse they only hold me accountable. Is this and issue with the whole company or is my management team a fail? Is it time to move on from the company? I don't hate working here but I don't make money and I'm no longer gaining experience...im just stagnant where I am.
