My personal feeling is using a more widely applicable pronoun is more respectful, in general, so I use 'they' frequently, especially referring to people I don't know and so where I don't know their identity.

Maybe the key here is a good work / team culture? I can also imagine some places or contexts in which the work might be more invisible / harder to attribute to specific individuals.
