I recently was told by my supervisor to hand in my resignation or get fired after my 6-month probation with a bad report. The last statement really took me aback, because it sounded more like a threat. And I had to verify by asking a follow up question: Would I still be terminated after 6 months with a bad report, even though I show significant improvement or progress. And they answered: It doesn't matter if you do improve, you will be terminated with a bad report.
For context, I had joined about almost 5-6 weeks ago. Generally took about 4 weeks just to get over the general onboarding details/reports/trainings/access/training/etc. During the interview, they had constantly brought up the concept of me being independent in my work, and I had answered yes because I was confident that if I was trained to do a task - I would indeed be able to do it on my own. Personally, once I had gotten trained, I do not need to ask for help after. Maybe I would make mistakes the first time, but I eventually would be able to understand what I did wrong and correct it immediately or the next time I do it. It was also a relatively new department, so when I finally came in person, there was one other person in the area; so a total of 3 individuals.
After I had gotten done with onboarding and trainings to gain access to the facilities, I had some issues with calculations - I never really liked math, however I can generally do it on my own using paper/calculator. However, that took me maybe ~1 week, maybe 1.5 weeks to get over - not saying I am the best at it. But I did not really need anyone to supervise me doing basic calculations. My only other coworker, who had to take on the role as my mentor, had also commented that I am showing progress. However, after submitting my data to my supervisor on Monday, I was asked to come into the office on Friday afternoon to "discuss my data". Of course, my data was never discussed. Instead it was a spiel of how I am not cut out in this line of work and that I should resign or face termination with a bad report.
Not to be surprised, I was very devastated. I thought I was doing really well and making progress as fast as I could. However, now I am coming to the realization that maybe I did cut off more than I could chew by joining a new department. However, I wish that they had not hired me from the beginning, if they were looking for someone with more experience. Because I had even declined another job offer that did not even care about my experience, because they were going to train me before I do any task on my own. The only reason I had chosen this, versus the other, was because it had more prestige, and I loved the direction it was supposed to go in.
My question is, would it look bad if I resign so early to my future job applications? I know that a short-term position such as this should not be included in a resume, but I did learn new techniques. Or should I just not mention this at all, and maybe consider explaining it off as a "bad fit".
Would appreciate any insight.
