I have worked for the same small company for four years.

I have worked for the same small company for four years. I have been told that I am essential and important to keep the company running. (Payroll, Finance, AP,AR, office management, some HR ) My duties have easily tripled since COVID and I'm often called to help in other departments. One year ago, we hired a new CFO, who instead of learning the programs we've been using for decades, changed out to all new programs. The programs are not working for us. I've told him multiple times that tasks that used to take an hour or two now take a day or two. My frustration is through the roof!

When I tell my boss, the CFO, that I'm overwhelmed, he tells me "hang in there" and cheers about how much easier it will all be when it's all "set up right". (We were told we'd be all set by Jan 2022, but it still is in testing phase and CFO has already cancelled all of our old programs) He doesn't help me get things "set up right" or back me up when I'm being ignored by coworkers that I need information from. He expects me to keep up the good work and "positive mental attitude" while I'm so frustrated I'm practically ripping out my hair. As of the past three weeks, CFO only works Mon-Wed and is adding more tasks to my already slammed agenda. Last I heard, he's looking into more new programs to start us on - the thought makes me want to throw in the towel. I am currently working 50-60 hour weeks and working from home occasionally on weekends. My annual bonus has been the same $200 for all four years. It is a fight to not bark at coworkers at this point because it feels like they all just send their crap work to me. (We've had employees snap before, and I'm not ready to be the next one.)

Please note: our HR department is a revolving door of yes-men who never last more than six months. The CEO is near retirement and rarely in the office anymore.

The pay is better than other local companies for the same position. I have respect of the managers for the most part. My work is known to be excellent.

I'm afraid that if I threaten to quit, they will just let me go. (Companies in my area are slow to hire and offer garbage pay for the work I do, but expect you to have a master's degree to work a coffee machine.)

I'm thinking about writing a letter to the Board of directors to tell them of my issues. I've gone to the head of HR once, who immediately went on vacation the next day and hasn't brought it up since (she's nearly 80 - forgets things often). I don't know what to do. I feel like I could stand on my chair and scream and no one would notice.

I know this is a tough one - any advice? TIA.
