She'd say something along the lines of 'i dont think its worth it' and 'there's way too much to be done in the lab' or 'its not the best time to go because we have this and this experiments running' etc

I've read some of your threads before PC.. you seem to be independent in what you're doing (/or were doing). Also, you seem to be quite authoritative! You do what you want when you want to do it! I wish I can do that same!!

Cheers for your reply.

Hi,
How do you tell your supervisor that you want to go on holiday?

Do you ASK for time off?
or do you just SAY 'i'm taking next week off'?

I have a feeling that if I ask her for time off, she'll start talking me out of it as she has done for other courses, meetings etc.

Then again, I don't want to seem rude and complacent about my research.

Cheers!
