What is the one thing at work you hate more than anything?

what i hate:
working for a company that says they care about the employees but treat you like a number
favoritism...
worrying about quantity over quality then bitchin about the quality
working evenings 2pm till 11pm (it has some pros and cons)
working on cars like an assembly line

What i like:
40+ workweek
weekends off (pretty rare in the automotive field in Northern VA)

actually having a job.
union-like benefits without paying a union to get them.
