I'm going to leave a job right after recovering a failed server
Did you give a notice? Why do you want to leave?
The shitty location, the incompetent boss and the late hours
I understand that not all jobs are great, but you still have to respect your duty, position, and everyone in the company. You need to give notice to your leaving to be considerate of their time and yours. You don't want to look bad to other employers.
I'm mad. I shouldn't have to wait 7 days to quit a job. I'm leaving right now.
Usually people give notice when they leave a job so their employer is not left in a bind. It would be better for your reputation if you could give some notice.
