The rights afforded to citizens generally apply to workers too - such as the rights to equality, privacy, dignity and life. But some sections in the Bill of Rights are especially useful to workers.

Section 23, the most relevant one here, is entitled "Labour relations" and reads:

    Everyone has the right to fair labour practices.
    Every worker has the right to form and join a trade union; to participate in the activities and programmes of a trade union; and to strike.
    Every employer has the right to form and join an employers' organisation; and to participate in the activities and programmes of an employers' organisation.
    Every trade union and every employers' organisation has the right to determine its own administration, programmes and activities; to organise; and to form and join a federation.
    Every trade union, employers' organisation and employer has the right to engage in collective bargaining. National legislation may be enacted to regulate collective bargaining. To the extent that the legislation may limit a right in this Chapter, the limitation must comply with section 36(1).
    National legislation may recognise union security arrangements contained in collective agreements. To the extent that the legislation may limit a right in this Chapter, the limitation must comply with section 36(1).
    
This section guarantees workers the right to fair labour practices, to form and join trade unions, and to participate in union activities and strikes.

Likewise, employers have the right to form and join employers' organisations and to take part in their activities. These groups have the right to organise, form federations and engage in collective bargaining.

The right to strike is written into the Constitution, but the right of employers to lock out their workers is not expressly included. However, the Labour Relations Act grants employers this right in certain situations.
