If the employee wins the suit he will regain his job, receive full back pay, and may even receive punitive damages. Unions are an important and highly politicized component of the labor market that are especially strong within the public and industrial sectors. The constitution and the Federal Labor Law both favour unionization. Approximately 30 percent of the Mexican work force is unionized, about twice the U.S. rate. It is imperative to contract a Mexican labor lawyer prior to hiring a work staff.
Unions tend to be very territorial, and by law, companies can only establish relations with one.
You should research the unions which represent your particular region and sector. The key to establishing good union relations is communication. Labor contracts are difficult or even impossible to change once established, so you should discuss in detail the plans and goals of the firm with the union representatives during the bargaining stages. For example, if you plan to implement any sort of productivity bonus system, it should be explicitly stated in the labor contract prior to signing. The goal of the unions is to protect the interest of employees, with emphasis on workers with more seniority.
