Before you get fired, ask for a promotion - Avis employé Marketing AppCake

I joined the company a year ago, at first I did the simplest tasks, during my work the checklist for tasks changed several times, because of this it was difficult to remember the information. After half a year I got bored doing simple tasks and decided to quit, but PM offered to take the position of a TA (to check the work of other employees) and salary revision, I had to wait a month, because there is a probation period because of the promotion. As a result, now I have a lot of work, I do a lot of different tasks for advertising. Did not have time to finish the task and asked to finish on Saturday, PM allowed to go out on Saturday. I plan to develop in this company, if there will be further revisions
