UNPROFESSIONAL BEHAVIOUR

I AM TRUELY DISGUSTED, THE COMPANY CALLED MY HUSBAND IN FOR AN INTERVIEW, TOLD HIM UPFRONT THAT HE HAS THE JOB, THE DAY HE WAS TOLD THAT HE GOT THE JOB HE RESIGNED FROM HIS COMPANY AND CALLED WILLOTON BACK TO ASK WHAT DOCUMENTS HE NEEDS TO GET SIGNED IN ORDER TO CONFIRM THAT EVERYTHING IS OK, THEY TOLD HIM NOT TO WORRY AND THAT THEY WILL LET HIM SIGN EVERYTHING ON THE 1ST OF DECEMBER. HE SUDDENLY GETS A CALL THE NEXT DAY TO BE TOLD THAT THE POSITION IS SUDDENLY FROZEN BECAUSE HE COULDNT START IMMEDIATELY. I DO NOT UNDERSTAND HOW DO YOU TELL SOMEONE THAT THEY GOT THE JOB THEN SUDDENLY CANCEL IT BECAUSE BY LAW A PERSON SHOULD GIVE ONE MONTHS NOTICE TO THEIR CURRENT POSITION BEFORE STARTING A NEW POSITION. HOW WILL THIS GET SOLVED NOW MY HUSBAND IS UNEMPLOYED BECAUSE OF THIS, THIS IS TOTALLY UNFAIR TO US AND HIM.
