wine grapes are different varieties than eating grapes. Just like cider apples.

By holiday do you mean strictly vacation or does that include holiday days like Christmas and new years?

Some employers do PTO others do separate vacation and sick. Generally I just count the combined days off – vacation, sick, and holidays when making a decision on an offer.

It depends on a lot of factors. For software development I’ve had anywhere from 4 to 6 weeks per year. One job was 4 weeks of PTO (includes sick time) and they only had 6 holiday days per year. That job sucked.

I too write in the notes “this is a notification, not a request”. It obviously depends on the type of job you have but I’ve never gotten flak for it.
