Pros

site management was good, just overwhelmed with huge workloads placed on them. employees at the site were good to work with. some senior management was great. others you heard their name randomly and you never saw them at a site, ever. especially sales .

Cons

sales is lagging terribly. low to no inventory most of the time. equipment goes months without even being turned on. investments to improve site conditions for employees in the warehouse seemed to take forever to get accomplished. its loud, dusty and smoky all the time. breathing in that soot is not healthy for you. site is hard to get to since its location in the city is dangerous. cranes that go right over your head with dangling loads of loose pipe is scary. pay is also very low for a company like this. we have had 4 mass layoffs in 5 years so stability isn't here. same with a rotating door of leadership. its a company that is circling the drain to a slow and eventual death.
