What's the whole point of signing up for a job .unprofessional they send you to jobs. But no guaranteed your gonna work. Pathetic company embarrassing to work here.I guess the reviews of not getting paid are very much true 3 Rd time lod has not paid me next day .. they always have some lame excuse. No offense to The owner but plz don't respond you apologies mean nothing if this has happened to me 3 times you are not doing your job. Nor your staff. Been waiting for 4 days for my check.
