How to make text in one line inside label with bootstrap columns?

Below label text is going in two lines.

How can I make label in one line without changing bootstrap columns as implemented below.


<div class="form-group col-md-6 fieldHeight">
<label for="erh" class="col-md-5 required">Enterprise Reporting Hierarchy:</label>
<div id="multiDropDownDiverh" class="dropdown col-md-7">
<input type="text" class="form-control" id="erh" ng-model="nonPersistentProcess.erhKey">
