I worked at Procter and Gamble as a contractor over 3 years, covering many different roles and obtained my first forklift licence through there and made some friends.
The pay was reasonable and the work varied from role to role. Some being physically exhausting and nearly impossible to do with the staff/equipment/time given, others you could do in your sleep, it varied wildly.
I was fired by Procter and Gamble, after 3 years for approaching the plant manager, whom considered herself to be approachable, and asking her for a permanent role as P&G staff.
Now i know what you're thinking, this sounds unbelievable and that i'm holding some info back, but i'm not, at one point I was seeing legal advice with the recordings that I had, but eventually decided that it was not worth fighting over a contractor job.
All in all ok if you want some part time work, but you may be treated poorly by permanent staff, that's life though.
depends on your outlook
