I started a job a week ago in a startup and I'm a bit of a slow learner.For now, I'm working in home and from next week we're gonna have our own office. The thing is I didn't mention that I already booked tickets, hotel and everything before I got this job. I have booked holidays for a week in another country.
This job is huge for me since I was unemployed for nearly a year so I don't want to have a bad impression at this one. I can't postpone my visit since my visa expires soon. I already a lot on this.
I'd like to tell him I plan on working on Saturday and Sunday to make up for the leave and I'd be willing to cancel the visit for the job. The office starts on Feb 15th and I was thinking of advancing my holiday plans to next week, finish my holidays and start working from Feb 25th instead of taking leave after joining the office. Is this is a good idea? I won't be taking leaves after that.
How and when should I inform my boss about this?
