Depends on your own situation and the official work situation. Do you have a contract that demands a certain amount of time or not?
Do you need their referral for another job or not? Will it show up on your resume?
Is it really easy to get another job?
Then there's how you feel about it all and your personality. I've once went to my manager, told him what I needed to stay. He had to ask the top, came back to me in an hour. I didn't get it, it was black and white. Fine. Then I'm gone. And I did, in the middle of the workday. Packed up my stuff and left.
My contract allowed me to do that so wasn't an issue.
Question is, if you know it's easy to find something else and you're not happy there, why are you hesitating?
I agree! I believe sometimes it's difficult because we want to do what's best, in other's eyes. Least that's what kept me from leaving my job sooner. I didn't want to disappoint others and wanted to do what I thought was right in other's eyes... a two week notice. But at what cost? The fast paced environment and physical demands of the job were making me miserable. It was difficult to enjoy my job while being in constant pain.
My manager spoke with me yesterday about lightening my schedule to make things easier for me. I finally spoke up and told her I couldn't do the job anymore, it's hurting me and let her know I'd finish out the week but then I'm done. She was very empathetic and gave me today off since it was a full day. Tomorrow, a half day, will be my last day.
Fortunately, I have another job that I will be starting next week. I worked there before so I already know I will succeed in that position. I think sometimes that's another hesitation when wanting to leave a job... will the next one be just as bad or even worse?
