it's like the trucking industry.
many times, companies offer hiring bonuses of "up to", $5,000 (paid in installments after xx number of months of employment)
but in the trucking industry, "job hopping" was the big thing to do, to find better paying jobs, benefits, miles, or hours.
but job hopping eventually hurts the employee, as a potential new employer thinks, "well, he won't stay here long, why should i hire him"?
i think this is what is happening due to the covid shut downs. people were highly dissatisfied with thier employer, so it was time to scatter and find jobs in different fields. so one area would see a rise in jobs filled, while other jobs, due to lack of pay, benefits, hours, still see low numbers of job seekers.
