It's not a secret most of people on this sub hate this worktype. I wanna get into details - why exactly, what are the biggest downsides and upsides of it.

Right now I'm a future IT student (taking my finals again in 3 months while working as a bartender 3-4 days a week for 8 to 12h) and I'd love to know how should I plan my future. IT is very often classic 9-5 work type (or even 9-7), should I be taking some steps to avoid it or just accept usual state of things?
