I work part time two days a week. I've been invited to a staff photoshoot taking place tomorrow, on a day I don't normally work. In most cases I'd go, but I've got another job lined up for January, so I'll probably be leaving soon. While the interview went great, I'll only be getting salary details and potentially signing the contract later this week, so it's not a done deal yet.
I don't think it would be right to go to the photoshoot and then put in my notice almost immediately after - those photos will be used on the website for the next year. And I don't want to reveal that I'm getting a new job before I've even signed a contract. Should I just make up an excuse not to go even though I'll risk my boss being upset with me?
