What sort of wage increases can we expect to see this year?

Despite calls to try to reduce job losses, it seems some unions are not going to be shy with their demands.
A national protected strike in the road freight and logistics sector is set for March 15, the South African Transport and Allied Workers' Union (Satawu) said in a statement on Monday.

The strike -- with regard to the wage dispute declared on January 28 -- would commence at midnight "and will be indefinite until our demands are satisfactorily met", Satawu said.

"The minimum wage remains very low and currently stands at R883,88 per week for drivers and at R579,16 per week for general workers."

Satawu has demanded a minimum wage of R6 000 per month for drivers and a minimum wage of R3 000 per month for general workers

That would be something like a 50% increase for drivers!

Whilst I like the idea of attracting a better calibre of driver to the industry (as a road user myself I would really appreciate that), I suspect this is going to be the wrong year to expect dramatic wage increases.

What do you think?
