Extremely safety concious workplace (with good reason) good working environment.
I worked as a contractor for SAPREF, their offices are located in KZN and I'm based in Pretoria. I was allowed to work remotely from my House and do scheduled visits to the site.
It is a very interesting site, they have many rules and strict policies to ensure one's safety.
I get more done when working remotely (minimizing time travelling), and I enjoyed that a lot, but it comes with some challenges. Communication for example, you can not run over to check something quickly with the customer, most of the communication is telephonically or via email, sometimes you do not get a response on email.
But it also forces you to have your documentation in perfect order.
Long hours / but fixed price contract.
