Creating an angled CSS3 divider - 100% / Auto height

Question

I have checked these two posts: Adjacent divs with angled borders? [duplicate] and Shape with a slanted side (responsive) but those solutions posted do not adjust to 100% height of the container and I need this. I cannot find a solution to fit my scenario.

I'm trying to replicate this behaviour the difference is the text inside this container can be of any height so I need the angle and container to adapt to fit any height (not a fixed height container):

Here's the code I'm using with a jSFiddle: https://jsfiddle.net/qzma0r6k/1/

CSS

section {
    position: relative;
    color: #fff;
}
.diagonal:before {
    position: absolute;
    content:'';
    -webkit-transform: rotate(45deg);
    transform: rotate(45deg);
    -webkit-transform-origin: 0 100%;
    transform-origin: 0 100%;
    top: 0;
    right:0;
    height:100%;
    z-index: 0;
    width: 50%;
    background:pink;
}

HTML

<section class="c-1">
  <div class="c-2 diagonal">
    <h1>Work with us</h1>
    <p>Scelerisque et parturient dis a erat cubilia congue sociosqu vel porta sem posuere a malesuada suspendisse id commodo. Dui consequat consectetur luctus odio nibh a vel sapien hendrerit ad a consectetur cursus a nisl posuere.</p>
  </div>
  <div class="bg-image"></div>
</section>

Something like this?

* {
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
  box-sizing: border-box;
}

.c-1 {
  background: #333;
  overflow: hidden;
  position: relative;
}

.c-2 {
  float: left;
  width: 50%;
  position: relative;
  color: #fff;
  padding: 50px;
}

.bg-image {
  position: absolute;
  width: 50%;
  top: 0;
  right: 0;
  bottom: 0;
  padding: 0;
  background-image: url(http://placehold.it/350x150);
  background-repeat: no-repeat;
  background-position: center center;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  z-index: 0;
}

section {
  position: relative;
  color: #fff;
}

.diagonal {
  position: relative;
  z-index:1;
}

.diagonal:after {
  right: 0;
  left: 100px;
  position: absolute;
  -webkit-transform: skewX(-15deg) rotate(180deg);
  -ms-transform: skewX(-15deg) rotate(180deg);
  transform: skewX(-15deg) rotate(180deg);
  content: "";
  top: 0;
  width: 100%;
  height: 100%;
  background: #333;
  z-index:-1;
}

<section class="c-1">
  <div class="c-2 diagonal">
    <h1>
    Work with us
    </h1>
    <p>
      Scelerisque et parturient dis a erat cubilia congue sociosqu vel porta sem posuere a malesuada suspendisse id commodo. Dui consequat consectetur luctus odio nibh a vel sapien hendrerit ad a consectetur cursus a nisl posuere. A cubilia varius dapibus non
