The field services division of the company is treated like mindless peons. You're expected to be available 24 hours a day to fix even the most mundane of issues. Your well being, rights, and employment conditions are only whats guaranteed by law and only if you forcefully remind management of said laws will they be that good.
Thoroughly unenjoyable excepting the customers. They're what keeps you going.
You'll gain experience
No work/life balance, low wage, no prep time for calls, No time for training, unable to use vacation days due to staffing issues, I could go on for weeks here.
