DeepMine is a company involved in the mining sector that is registered in the UK. It has subsidiaries in various countries including Zambia and Nigeria. In recent years, DeepMine has been accused of harmful working conditions in its mines and the negative effect that mining activity has on local communities around the mines. Recently, various groups filed lawsuits against the company in the UK to seek compensation for the damage caused. Employees working in the mine have claimed to be suffering from serious health problems due to inadequate equipment in the mine. Furthermore, members of the local communities claim that the contamination of the land around the mine due to the extracted materials makes the land unsuitable for agriculture. Based on the case law and doctrine studied, please advise victims of the following scenario: DeepMine employees who have suffered health and safety issues are employed by a legally separate subsidiary of DeepMine which operates a coal mine in Yorkshire

Can you also advise employees on whether they can rely on the code of conduct to incur the employer's tortious and/or contractual liability?
