Currently serving 2 months notice period, reason being received an offer with better pay. I'm somewhat slacking off in terms of doing my work on my own time and don't care much for deadlines. This is my first job of almost 6 months, so I did made some errors when processing invoices. Clients made complaints for both not meeting the deadlines and failing to perfectly do my work.
I just don't have the energy to care now and just clocked out at 5 like usual with the tasks overdue. The supervisor keeps on getting stricter with me lately (which I did expect to get). I'm aware that my team are starting to have negative views on me. They expect me to juggle every tasks and do it perfectly because they can. Most of them have worked there for years.
I'm currently pursuing my studies part-time and would usually use that for most of my excuses when they want me to work overtime. I think that I should just focus more on my studies currently while waiting for my next job. At least I still go in the office 40 hours per week and do my work as usual.
Maybe this is unprofessional and would cause me to have shitty references. Really doesn't bother me much though because I already have a job offer lined up and have enough money as buffer until that new job.
