So I've been working at a company about 2 or 3 years, and during that time I feel like I've been working an over-average amount. Vacation time, while allowed, is more or less entirely discouraged - I've taken a day and a half of sick time in my entire tenure, and 2.5 days of vacation time (when I requested the time off for a trip, I was asked if I could come in the first half of the day before my flight left).
I typically take short (20 minutes at most, sometimes I don't leave the office at all, but just make a sandwich at my desk) lunches
I typically work 10 hours per day (which usually actually means 11 hours, occasionally more), four days a week, but lately I've been being asked to work a lot on a fifth day as well - usually between 6-10 hours extra, and it's usually happening every two to three weeks now. A few weeks ago, I was sick, and instead of taking a sick day, did a 60 hour week because we had to rush something for a client.
I could put up with this for some time, but this schedule has made me tired, and it has made me hate going to work. I feel like I pretty much do nothing but work now, and I really feel like my productivity is completely destroyed.
How do I express this to my boss? Is there a tactful way to say, "you're burning me out", that doesn't lead with me being fired? My assumption is that he feels the extra work is due to incompetence on my part (I feel it's a mixture of screw-ups mixed with a complete lack of a business process, and also it's hard to stay focused on some days when all I want to do is go home and just sleep), but honestly in that case I'd probably just prefer to be fired.
How do I tactfully say this? Is there a way? Is the only solution getting another job?
