Here’s what I like about employers – it’s the ability to instantly switch from "you’re obliged to "T" to "I’m obliged to do everything that’s written there" and vice versa.
Past work (state office on a federal scale).
We work alternately (from eight in the morning to lunch or from lunch to midnight) and on a sliding schedule, but the contract is written "from nine to five and five days", because otherwise you will have to give extra days of leave and calculate the salary differently, and the bosses do not like it.
But as soon as the employee comes to ask for a walk away - it immediately turns out that the law is not required and in general he was overwhelmed.
