im afraid this is what companies do nowadays,and if they go through the right legal procedures then your husband has not got a chance of proving otherwise,my son has just been put through the redundancy process,along with 2 others,the company were intent on getting rid of 1 person,everybody knew who it was and at the end of the process,it was the one they wanted rid of,that was made redundant.
but as you say,its not a nice way of doing things,but as hes been there 11 yrs,i would think the ones who have been there for shorter times would be the ones to go,it will cost them less money
and by the way,when they got rid of the guy at my sons work,they took on 2 more people doing the SAME job.as i said,if its done by the letter of the law,then its quite legal
