Pros

Really decent benefits ,GRATE Facilities ( Building Maintiance) Supervisor, GRATE Director that is in charge at out 2 Tempe properties! I love the company work environment

Cons

My interview and job offer were around the first of the month, I was told by HR That My start date would be as soon as I was able to accept the job offer and once my background check came back. I was called back a few minutes later and asked if I could start almost 2 weeks later........Unknowing that my start date was the last day of the facilities tech's that I was replacing. So I LITERALLY GOT 2 1/2 hours on a job that has Weekly, Monthly, Quartly, Semi annual and annual inspections on some appliances, Systems and areas that I was and am not familiar with or that Vendors were called in for at all the other facilities that I work for in all the yeaars I have done maintaince for in the past. So I have to ask questions ALL the time because I did not receive a proper 2 week training period, Why I was hired this way I do not know but feel I was setup for failure and am under constiant stress, and feel like a TOTAL failure because I am running behind 100% of the time. I take care of my 80 year old father who has onset dementia when I am not at work. So no real training and being behind all the time has taken its toll on me mentally and physically. ( This has only been MY PERSONAL exp. I am told IT'S NOT COMMON practice )
