Dealing with a toxic advisor as an undergrad

So,

I can't believe I have to actually write a post like this, but I need help.

I'm an undergraduate working in a paid research position for a pre-tenure PI at a well-known private research university in the northeast US. I love the work I do, but the relationship I have with my boss/advisor is degrading to a point of complete nonfunctionality and I'm not sure what to do. 

Everyone in the group has long had issues with his management style - he micromanages and yet complains that you don't get anything done, tells you not to set up certain experiments and then complains at you for not doing what he told you to not do. He routinely texts us at 2AM to chastise us for little things we did wrong in lab. Perhaps the worst part of it all is the constant attack he exerts on our work ethic - he has complained to me I don't work hard enough when I hadn't slept in two days. Working in his lab more than I am technically able to by university regulation on top of a full course load in a demanding major and nothing I do is good enough for him.

Today he texted me explaining that his expectations are that I work no less than 72 hours per week with the level of productivity that would be expected of a postdoc at a big-name group at an ivy-league university. 

I swear to god I am not making that up. I have the texts. Again, I am an undergrad. I love the science. I love what I do. I intend to go on to grad school, and I'll quite frankly need a letter of recommendation from him to get into a good one. But I am at my wit's end dealing with this dude. What do I do?

Private texting of an RA just reads like a warning sign, especially in parallel with expressing extreme expectations that are in direct conflict with University regulations. Nothing you could get out of a good letter from this person is worth this, especially if it continues for others.

You need to take this up with someone who you can trust has student safety in mind. One option is another professor in the department, or the chair, if you feel like you can trust them to listen to you and recognize this behavior as inappropriate. This is good because they might be able to vouch for you in a letter to explain the situation down the line. If you’re concerned that people in your department might agree with the advisor’s priorities and behavior (horrifying but possible), you should talk to the administration at some level. Some universities have an Ombuds office who is responsible for handling anonymous student-faculty conflict. You might also reach out to a director of research or student employment. Apart from bad mentorship this looks like exploitation of power over student labor, plain and simple.
