I worked at JELD-WEN full-time (More than a year)
People were great to work with. Pay was decent.
Unreasonable expectations from higher management. Too much micro-managing. Too much mandatory OT for salaried people.
Advice to Management
Listen to the people doing the job. You may learn something.
I applied online. I interviewed at JELD-WEN (Charlotte, NC).
Misleading, deceptive, failed to follow up, failed to meet commitments and then went dark when I followed up - fortunately Mickey Mouse firms who treat people like this can't hide their warts forever and eventually no one want to work there. You get what you give.
