Mainly they hire through a temp agency, this allows them the flexibility to pay you $10 hr and terminate at will, without any reason. These days, Glock keeps a constant rotation of temporary employees through different staffing agencies. They will make an agreement to hire after 90 days, but currently, many of the employees that remain (i.e. if they haven't been terminated before or after 90 days) lasts over a year without any offer of full time employment.
