quitting

i’ve only been working for about 5 months, and honestly, i hate it so much and i just can’t see myself working here any longer. i have found another job, and i genuinely don’t want to stay another 2 weeks at this job. besides, it’s not like they publish the schedules in advance, they come out literally saturday before the next week. can i just quit without putting in a 2 weeks? i don’t know how it works…
