Long hours, and they nickle and dime you wherever they can. Commission based pay (Which is better than hourly if you're experienced and not lazy...). For all the new people in the industry they'll be lucky to make minimum wage. Lots of "free" things you're expected to do. Call backs, meetings, drive time, truck setup. You'll waste on average 2-3 hours a day not getting paid with the commission setup.
Contract is based on a 5 day work week, with 6th being a bonus. (10% when I worked there). But skip a Saturday (even when your production goals are met and your week is "DONE") and your pay is slashed by 15-20% due to "missing a day".
It's all about revenue and production. Upper management will flat out lie and BS you. They will work you into the ground without batting an eyelash.
Massive turnover (over 330 new employees to fill 30 positions the first year I worked for them). Well over 200+ the second year I was there.
They'll also force you to break quite a few laws set down from the Ministry Of The Environment. Quite hefty fines to you (the technician/exterminator) if you're caught 'doing what you're told'.
Probably why they went from 25,000 customers in 2006, to 16,000 by 2012... :)
