This strategy is commonplace anymore. Very few manufacturing companies within Aerospace that once paid employees a fair wage are now expecting much more while paying much less. This is why turnover is so high and production and quality suffer. Get what you pay for !
They start you out low ball, tell you after 90 days you can have another review and get paid such and such, it never happens. I waited about two years before I got paid what they said I would in 90 days. Story of most people.
The pay is bottom dollar, you only make more because of the mandatory 11 hours they require everyday once you pass your inspection test.
