To not bother contacting work

[RogueRebel]

I work two long days a week and have spoken to my manager re holiday for school starts. It was agreed and he's given me 3 days off. The week before I went on holiday there was a hoha because I checked the Rota and my holiday wasn't logged. I then had to contact the manager to check holiday was going ahead, it was and I was told the 3 days.
I popped into work a few days ago to get some things and checked the rota again - no holiday for 3rd day is recorded! There was no managers I could talk to about it.
I've tried calling (no answer or answer phone) but now I'm annoyed its not my job to do the rotas and holiday has been verbally confirmed via phone should I just ignore it now and wait to see if I get a phone call?
work place is notorious for bad Rota planning and changing shifts at short notice without telling staff of changes and this has lead to staff not showing up.
I'm pretty good at keeping an eye on this and the only issue I've really had was trying to leave early one shift but I checked the Rota and realised before this happened.

Can you email anyone? I'd definitely not just leave it, you know it hasn't been recorded so you are only going to get into trouble if you don't sort it out. They do sound useless though.

I would send an email to the manager/managers concerned just to cover your back and then just leave it. If its questioned you can say, quite truthfully, that there was a rota cock-up before (true), that you spoke to the manager about it (true) and that on discovering there was a second rota cock-up you emailed to make it clear that this holiday had been booked and this wasn't your fault.

Always better to take belt and braces approach imo. No reasonable person would conclude that you hadn't been responsible about it after that.

there is no emailing system at work unfortunately or I would do that. its been 2hours now since I would normally start and no contact from work. which suggests they've realised its there mistake.
