It means that each time your husband ( I assume he's the visa holder) wants to leave the country - he needs to get his company permission. They can register his exit visa on-line in literally a few minutes. To go on leave, he's probably had to fill in & approved his leave anyway?
As a "trailing wife" there's no restrictions on you once you are set up on his sponsorship ( couple of weeks ) .
While it seems awkward to have have your company permission, the fact is that you need your company permission for most things anyway.
You'll get used to it & it's normal for this part of the world
