Just been fired

So I’ve just been fired.

I’ve just finished my 2nd month, where I admit the first month wasnt the best but I improved very much so in my 2nd month in terms of the management accounts. I feel very hard done by.

The finance director mentioned me asking the finance manager about where this certain accrual should be posted. It was a bonus accrual for a directors loan, I’ve never dealt with payroll before which btw I mentioned in the interview.

There was also a confidentiality issue where I was having a friendly chat with an apprentice and I asked him what money he was on, which he told me and then he asked me. He has then spread it around the office which has caused problems.

What do you guys think, do you think I was hard done by or do I need some more training? What are my next steps?
