Probably should have did the two weeks notice, 2 weeks ago knowing it would be a holiday weekend and you might actually go somewhere for the holiday.
If you put in your notice to quit before the Holiday weekend, they would be upset but you gave notice and they have more time to allocate the hours to someone else.
Notice to quit and call out on Holiday weekend 😡
However the only way you could be saved in this mess is if you had a job lined up and no intentions of returning to Spot.
