Absolutely I read the contract!
And there are many things that are far from ideal with it as I am sure you are aware but I am not going to digress.
However, most contracts (all that I have ever signed) say something along the lines...entitled to 'x' amounts of days per year to be taken subject to availability/agreement etc etc
BUT does that make it SAFE or right that in a western country in the 21st century that there are people out there for 18 months without a vacation or a break.
