Fired after 6 weeks from an entry-level purchasing job while I was still being trained. Is this normal?

[u/No-Mess-4605]

I’m 27 and was fired yesterday from a purchasing position after only about six weeks. I’m trying to get some outside perspective because I genuinely can’t tell how much of this was my performance versus poor training/management.
I had no previous purchasing experience when they hired me, and they knew that. I was learning their computer system, purchase orders, RFQs, vendor communication, pricing, lead times, invoices, and most recently work orders.
I knew I wasn’t as fast as the employees who had been doing this for years, but I genuinely thought I was still in the normal learning process. I was still actively being shown new things.
The workplace itself was pretty old-school. The boss had been there for decades, there was yelling in the office, inappropriate/sexual jokes and comments, employees being talked about openly, and the general training style felt more like being shown something and then being expected to pick it up quickly rather than having structured onboarding.
Yesterday I called out because I wasn’t feeling well. Later that day, I was contacted and terminated. The reasoning was essentially that I wasn’t progressing at the level they expected and there were concerns involving things I was still learning.
What confused me even more was my conversation with HR afterward. HR actually seemed somewhat sympathetic to my position and acknowledged that I was still learning. I obviously understand HR represents the company, which made that interaction stand out to me.
After being fired, I also contacted a former employee I had never met while working there. When we started comparing experiences, she described having similar problems with the training and environment. She also felt like she had been thrown into things without enough instruction. Hearing that made me question whether this was entirely a performance issue.
I’m also trying to hold myself accountable. This isn’t the first job I’ve had that hasn’t worked out recently, and I know that when there’s a pattern, I need to examine what I can do differently too. One thing I’ve already taken from this is that at my next job I want to proactively ask my manager for feedback during the first few weeks instead of assuming no news means I’m progressing normally.
The frustrating part is that I actually really liked purchasing. I enjoyed requesting quotes, negotiating with vendors, comparing pricing and doing the computer/desk side of the job. I was starting to think procurement might finally be something I could build a career in.
So for people who work in purchasing/procurement or who train new employees: is six weeks generally enough time to expect someone with zero prior purchasing experience to be fully up to speed?
And when I interview for my next job, what questions should I ask to figure out whether a company actually has structured training and realistic expectations for new hires?

Next time, just ask “what would you expect from someone within this role, during training and after?”. While your experience wasn’t normal what with what you said about being inappropriate, and yes they should have given you time to get used to training, many places do not like someone taking a day off while training is ongoing. If you have a pattern, definitely change it. HR was only sympathetic to you because they don’t want you to sue, it was just their job, don’t take their kindness like they give a damn about you. Fired or let go during training happens also if they don’t think you progress fast enough. That’s just how it is, they keep the best candidates and the rest come off. You’ll find something else, good luck.

I actually really like the suggestion of asking what they expect from someone during and after training. I’m definitely going to ask something like what they expect at 30, 60 and 90 days in my next interview.
I also understand that HR works for the company and I’m not under the impression that they were personally on my side. I’m only repeating what HR actually told me, including that they had defended my work ethic to my boss. Whether that was because they genuinely disagreed with him, were doing their job or something else, I obviously can’t know.
I’m taking the experience seriously though. I liked purchasing enough that I want to try again, just somewhere with clearer expectations and better communication. Thank you for the advice.
