You can, and I have, but it's customary for 2 weeks so there is time for finishing tasks, writing docs, performing knowledge dumps, etc. I've left a toxic job effective immediately. But, if it's an "ok" job that I'm leaving, giving 2 weeks is a good way to keep a positive relationship. I've left just for more money, or to have a shorter commute. In which case, I'd like to keep a positive relationship with those companies in case I ever want to go back. Not giving 2 weeks is a red flag for our HR friends Also, as an employee, those two weeks are easy-street. Leaving early and long lunches are the norm.
