You will give and give and give and get nothing in return, literally nothing. When you get an offer and you see the contract, that should tell you everything you need to know, all the warning signs are there and alarm bells should be ringing. This place is extremely stuck in its ways, they will dictate where you work (and you cannot work anywhere but your “uk registered address”). Once you book your leave, that is the nail in the coffin, you cannot make changes. If you haven’t booked your leave for the year, be sure that they will hound you from the beginning of the year to do so. Every request you ask of them, no matter how small WILL be met with resistance so be prepared to fight tooth and nail if you want it. Extremely stubborn, uncompromising and want to control everything. The annual leave, versus the hours, overtime and all that you give for nothing in return will destroy your soul, leave well alone. You have been warned.
