The chosen answer seemed to work most of the time, but in some iOS devices it was not picking up the contain: layout; setting, making the label not align. I didn't need my label as part of the clickable button, so my FAB label addition is below which works on iOS. Fairly simple.

HTML

<ion-fab top right edge>
    <button ion-fab color="primary">
        <ion-icon name="add"></ion-icon>
    </button>
    <ion-label>Scan</ion-label>
</ion-fab>

CSS

ion-fab ion-label {
    font-weight: bold;
    color: color($colors, primary, base);
    text-align: center;
    margin: 0px !important;
}

For what it's worth, I was able to accomplish what you ask with the following SCSS.

It'd be nice if this was supported directly by Ionic, but I can't find anything indicating this is built-in.

    button[ion-fab] {
        overflow: visible;
        position: relative;

        ion-label {
            position: absolute;
            top: -8px;
            right: 40px;

            color: white;
            background-color: rgba(0,0,0,0.7);
            line-height: 24px;
            padding: 4px 8px;
            border-radius: 4px;
        }
        contain: layout;
    }

ross solution is great,but in order for it to work on Ionic v2 I had to change the .fab class that comes with Ionic from contain: strict to contain: layout.

This is how the class is originally:

.fab {
    -moz-appearance: none;
    -ms-appearance: none;
    -webkit-appearance: none;
    appearance: none;
    position: relative;
    z-index: 0;
    display: block;
    overflow: hidden;
    width: 56px;
    height: 56px;
    border-radius: 50%;
    font-size: 14px;
    line-height: 56px;
    text-align: center;
    text-overflow: ellipsis;
    text-transform: none;
    white-space: nowrap;
    cursor: pointer;
    transition: background-color, opacity 100ms linear;
    background-clip: padding-box;
    -webkit-font-kerning: none;
    font-kerning: none;
    -webkit-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    contain: strict;
}

So, add the following on your page .scss file:

.fab {
    contain: layout;
}

It will overwrite the default .fab class for the page and it will work.
