I’m a recent graduate looking at accountancy and finance roles. A few years ago I got a job as an operative but had my contract terminated because of absenteeism.
would this be found out by my future employers through background checks even though it will not be added to my cv? What type of background checks does the big 4 take?
How long were you in that job? Would a gap in your CV be noticed?
They won't know that you worked as an operative unless you tell them, or it is available maybe on social media or LinkedIn. There is always the possibility of some personal connection in Ireland - see if you can check out who audits the company you worked for, just in case.
I was only there for a day.
I was on payroll with them, wouldn't this be seen if they check my revenue using my pps number?
You were fired for absenteeism after one day?
No, new employer won't see anything about past employers.
Likely showed up on the first day, didn't like it and never showed up again. Fired some point afterwards.
Any manager would have to fire you if you only show up for one single day and then never again. It's not even absenteeism, but most likely a breach of the employment contract. Getting fired is and would in such a case be the legal termination of the employment. However you could have verbally told them you didn't like the job, it's not what you'd expected, and left officially on the next day.
I don't think this has any impact on reference checks. These checks are often done by external companies, the work is repetitive. In some businesses it's part of the process of getting hired, only to say they have a process in place. If they want to hire you they'll hire you regardless if you'd be fired once, or have one bad reference, out of many good ones.
