Do you think this is fair or right for employer to act this way?

Laurel Asked: Do you think this is fair or right for employer to act this way?

My husband has been out of work for a week because his boss sent him home last week with instructions to call him in a week to see if he will remain at his job.His boss has not returned any of his calls.My husband's income is the only source of income we have to provide for our two children since I am a full time student.We greatly depend upon his income.
Upon the boss sending my husband home, he said it's because he is too productive and he cannot believe that he can work like that. The other employees verify that he works hard and is the best at what he does. My husband tends to work at work and doesn't "milk" the clock or the pockets of the companies that hire the boss' company to do a job.My husband has been doing his job for 5 years with different companies and always gets great reviews because he gets the job done and gets it done safe (he has always been accident free).He often works 60 hours a week – just as all the other employees do – but unlike the other employees who dilly around on job sites and pull half the amount of loads that my husband does, my husband does not dilly around and uses his time to every advantage to get more done.There are days when the boss' list is incredibly long and will require the employees to work from 7 am to 9 pm.On these days, which have been very often lately, my husband really likes to step it up and really work hard to get the list completed so they do not have to stay at work, working in the dark, driving at night, and so they can get home in time to get good sleep so they can get back up in the morning and be back to work at 6:30 am.The day my husband got sent home was the day after he completed almost triple the amount of work the rest of the employees got.The other employees were thrilled about this because otherwise they would have had to stay out until midnight to finish the job.Because of how much work my husband did, the employees got to clock out at the usual time.Plus, the business that hire the boss' company are happy because the job is done and production is up.My husband has actually gotten the boss' company work because he works for this company and they know the job will get done.Now, my husband is sort of being punished for working too hard – for getting the job done.Worse yet, the boss seems to be totally avoiding the situation by not returning calls.This seems really unprofessional and almost childish.It has left us uncertain about how we are going to pay our bills in the next few weeks since the company does not have sick or vacation time – every day that my husband is out of work, hurts us badly. There are not a lot of jobs in this area that pay nearly as well and I am actually thinking I need to drop out of school, put the kids in day care and go find work too.
I understand that the boss literally wants the employees to "milk" the clock so it puts tons of money in his pockets, but that does not seem to be ethically right to do all the time – nor does it allow these employees who are CDL drivers to get home in time to get good rest.They have to be at work at 6:30 am and often do not get home until 10 pm and they all work a rotating 5 day on 2 day off schedule.
Do you think the boss is being fair or professional?What do you advise?
