I've found similar questions here, but mine is a bit different, if not please correct me. Right now I presented a resignation letter where I stated that because of my university studies schedule I had to resign because time wasn't proper. I didn't talk to my boss or human resources deparment because some months earlier they told me policy was if they gave me hours for studying I should recover them on another day, but that wasn't possible because I required at least 8 hours permission, and that is a work day.
Boss told me I should have talked to him before presenting him the resignation letter, and two days later they proposed to keep me employed discounting the hours I took from paycheck. After thinking about it, I agreed.
It was fine but a week have passed and pressure is rising, because I have to rush on tasks to complete them with less hours at work. I want to present a new resignation but I don't know how to handle this, since they aren't proposing this arrangement to anybody else.
