Our body of employment law is there to help both the employee and the employer, so neither should hesitate to take advantage of it. But keep in mind that some aspects of it are there to protect the general public's interest, and that the government can use them against you if you don't follow all the rules.
If you're in a situation where you have to hire a specialist in employment law, don't go for the lowest bid unless you know they can provide exactly what you need. Lowballers often provide less than exemplary service, which could be a serious liability in court.
