Advantages and disadvantages of trade union membership
Advantages
Trade unions aim to protect workers. As a member, you can seek advice and support from trade union representatives or from the local trade union office.
They are experienced in negotiating with employers, and have a good knowledge of workplace laws. They can also offer you legal protection.
Disadvantages
Trade unions take industrial action based on the votes of their members.
You may disagree with the outcome of a vote, but feel pressured to be involved in the action. If you go on strike you will lose some of your pay, and experience the stress and pressure of having less money.
The company will expect that you catch up on your work when you come back after a strike.
