Leave Industry for Ph.D. without Burning Bridges I have been working for one of the big tech companies for the last year, but I plan on leaving in August to start a Ph.D. The company I work for has a reputation for not always treating all of its employees well under all circumstances (e.g. making people they don't like miserable until they quit), so I am very wary about letting anyone know of my plans to leave until two weeks beforehand. On the other hand, I have a manager and mentor that have done a lot to help me in my current job, and I have good relationships with them that I would like to keep. Leaving with only two weeks notice will certainly have a negative impact on both of them, and I would like to avoid that if possible.

other relevant details: 


I don't think any of the coworkers in question would support my decision to do a Ph.D., as the way to get higher up in this company is to stay in it, not to leave to get a Ph.D.
I don't ever plan on returning to industry, but it still seems like a bad idea to burn bridges


Can I ensure no negative impact on my coworkers while also ensuring no negative impact on myself?
Be sure to consult your employment contract.

The professional thing to do is to give two weeks notice.  It is your manager's job to be prepared for the departure of employees.  You are not responsible for that job beyond giving the two weeks notice.  

If the company treats you poorly during the two week notice period, all you can do is offer to leave immediately.  In that case you may loose two weeks pay.

Thank your manager for mentoring.
