Let me vent a little

I really want to lecture my superior. We're always short-staffed with part-timers, and this is the Silver Week holiday. You can easily imagine that I'm the one handling customer service instead of part-timers during this period, without you needing to be told. But, the deadline for the report you requested was before Silver Week started, right? It was you who submitted it after Silver Week began because you couldn't make the deadline. And it was you who submitted it in a way that required confirmation, with some deficiencies. So when I sent you a work LINE message for confirmation, you can't check LINE? If that's the case, please submit it before the deadline properly? Or, add a note in the submission email stating that this is a special case and it's definitely correct. Then there would be no need for exchanges on the work LINE, right? Stop reading messages without replying? If you don't have time to type, call me when you've read it? Given your position, you should be allowed to go into the back office for 5-10 minutes between customers for administrative tasks, right? You can make a call there, can't you? This is such a waste of time... I wish you'd stop.
