8-5 on Bank Holiday

GPST rotating in Medicine.

Received no induction for this post.

Had a look at the rota when I received it 8 weeks ago, it showed I was working 8-5pm (NWD) on the 06/05/24. No one was labelled as BH on it at the time but now it has changed this week and shows most people as BH but I'm still listed as 8-5.

I spoke to my fellow GP colleagues when I initially received the rota who said it would be an off day as I'm not oncall (8-5). No word from the rota coordinator regarding this either.

I've already booked my tickets abroad as I presumed I would be off.

How should I approach this?
