Pros
Well resourced High standard of colleagues Positive stance around BAME / LGBTQ / Wellbeing / etc Prestige of working for big name in the industry When things go well, you're a star...
Cons
... when things turn, you're out. I had a number of really strong years when the books sold brilliantly. One bad year (during which HUK had re-organised the sales team and moved warehouses, both times with massive knock-on effects to sales) and I was made redundant with little ceremony (the MD of the division I worked for didn't even take me aside to say they were sorry it hadn't worked out). Sales teams very disconnected from editorial / publishing teams (and getting more so thanks to recent restructure). If you're not publishing an established brand or an expensively-acquired high-concept debut from a 'promotable' author - forget about it. Your book isn't going to get pushed. All of the warm words and actions around wellness, looking after their people, etc, become slightly irrelevant once you've been booted out.
