Questions about this role
Both have a role. The contractor reviews employment matters, and the company reviews work quality and safety on its site. Agree the split in writing and confirm contract and legal responsibilities with your adviser.
Use a short site induction and a sign-off sheet for each new worker, and keep a skills list so strong workers are kept for repeat jobs.
Attendance, work done, toolbox talks and payment records, kept with dates. Confirm what the law requires you to keep with your adviser.
