 After a few went out of business, there was a labor dispute and 200 employees of the Gray Cab Company went on strike.While Montana was never publicly linked to the strike, rumors were made back in 1932 that his associates instigated the Gray Cab employees to strike for more wages, ultimately causing the company to temporarily stop transporting passengers.While Montana's alleged role in the labor dispute was unknown, he faced his own labor problems less than three years later when some of his drivers went on strike.
