How restrictive can these things be in Texas? Can an employer keep a plumber from going to work for another plumbing company? Or a car salesman from selling cars somewhere else? I can understand Company "A" wanting make sure an ex-employee doesn't use their software (or other proprietary information) at Company "B" but what else can an employer do? The next job I go to may not be the one I want to stay at for the rest of my life.
