NC for obvious reasons.
I told a lie at work recently, basically I made an excuse to an external person as to why I was late with a piece of work.
The actual reason is that I found the work more time consuming/ more technical than I'd anticipated and I failed to leave myself enough time to prepare it so I missed a deadline by about an hour. This was my first time completing this piece of work and I had thought I'd done enough prep beforehand but obviously I was wrong. Lesson learnt and I will not make the same mistake twice.
However, I hate being late, I always put pressure on myself to make sure my work is to a good standard and this is the first deadline I've missed like this and I'm in a fairly new job so I was properly panicking trying to get it out on time. Like out in a rash level stressed. And I made an excuse and lied about why it was late. So fucking stupid and I wish I'd actually just been honest or just more vague. I never lie, this is totally not like me and now I'm actually panicking I'm going to get caught out and it will be worse for me. I'm so cross with myself and now I'm stewing on it and can't let it go. I was honest with my boss about missing the deadline but I didn't mention the excuse I told the external person.
Do I go to my boss and say what I did or do I just leave it and hope that it doesn't come back to bite me. Feel like such an idiot.
