I am a plumbing subcontractor working on a commercial job for a GC. The GC is refusing to mail my payment to me (which is already 30-60 days overdue) unless i sign an UNconditional waiver - or they refuse to mail my check. I tried to explain how the waivers (unconditional/conditional) work- but they are obviously do not understand the concept. They keep telling me they refuse because they can't leave themselves unprotected and it would be "bad business"- and that I am the "only sub on his jobs that seems to expect these 'special conditions'" and that I am "misconstruing the lien laws." We are only halfway through this pretty sizeable project-and I would rather file a prompt pay act violation than filing a lien-it's not the property owner- I know the owner has paid the GC- so I am not looking to make problems for the owner if not necessary.- but the pay apps were approved long ago and there are no issues with my workmanship- it is all the GC just not wanting to pay me. I am about to have a meeting with the GC and they have stated to me they REFUSE to release the money to me without that unconditional-so I just want to have my "ducks in a row" and say with utmost confidence that they are wrong- and it is breaking the law to hold my money for ransom for that waiver
