I see exactly what you are trying to say. I have moved a few times from facility to facility for mainly pay and better schedule offerings.
However, many people may be stuck in a rut where they are at, mainly because of benefits. They may be the sole benefit bread winner for their family and cannot afford a lapse in benefits to take another job where health, dental, etc. may not kick in for 30-90+ days. PLUS positions for nurses within a system or single hospital facilty far outnumber those that a mere laboratorian are apt to apply for ( or have a chance of getting).
Looking at a number of positions posted locally at a few facilities in our area, positions that I may have some interest in have qualifications that are not covered by a MT background, or many say Information Tech, RN, BSN, etc required. Many of these are for educational, instructional, IT, etc. positions that offer far better opportunites than a laboratory position. Unfortunately, many laboratorians are unable (for a variety of reasons) to be able to further education or skills to be able to have a shot at these positions.
I keep hearing the looming shortage will drive up our wages... the looming shortage -- pish posh.. the only amount my wage goes up is the pittance yearly COLA. LPNs make as much as we do.
