A sample answer to question 1

How do you balance protecting the organisation with treating employees fairly in an Employee Relations Manager role?

I don't see them as opposed. Fair, well-documented processes protect the organisation because they reduce legal risk, and they protect employees because they know decisions are made on evidence. My job is to be the person who asks 'have we followed a fair process, and could we justify this decision to a tribunal and to the employee's colleagues?' I advise managers on what they can lawfully do, but also on what is sensible, since the legal minimum isn't always the right answer. For example, a technically fair dismissal might still damage trust if people think it was handled badly. I also look at patterns, such as repeated grievances in one team, and raise root causes with the business, rather than just processing cases. I'm clear with employees that I represent the employer, but I'll make sure they're treated with respect and that their concerns are properly heard.

Common mistake to avoid: Presenting yourself as purely management's protector; ignoring how decisions feel to employees
