while working for shawn krestar at krestar contracting i was surprised to see shawn and his brother shane crushing and snorting perscription pills on the customers property.shawn sub-contracts for mihalko contruction from altoona pa. im sure they would not be happy with his and his crews actions of illeagal drug use on the job site.then to top it all off he owed me 1100.00 dollars for two weeks worth of work.he gave me 400.00 dollars and told me thats all the hours i have.that is totally false cause i was there every day and times he was.he couldnt pay me because ha had to pay his dope man.mihalko should know of this behavior on there cutomers properties.something needs done before someone falls to their death from a roof because of illeagal drug abuse or a home owner does not get the quality of work or timeing of the work due to their neglect.please help.thank you.
