The SDA organisers are always there to help, If I have a question no matter how important or unimportant I think its is, I just call them and they help me...It's that simple!
I think the question should be this: Why should somebody not join the SDA? That list would be short.
I call the union for handling problems if I ever have any in my workplace, they always respond in a fast and timely manner to help resolve them!
Free advice, assistance when required, negotiators improving my working conditions, discount vouchers and competitions - why wouldnt you be a member??
