My friend has two children to her ex partner and he hardly sees his kids. He tells her he works away in the Shetland islands for 3 weeks doing 12 hours shifts and doesn’t have a single day off while he’s there. Then he’s only home for 1 week and has her children for 1 night on that weekend. Our other friend says this is illegal to work that many hours without a day off and he must be going home every weekend and just lying to his ex so he can spend more time with his new partner and kids. Does anyone know if you can work those hours ?
