My question involves labor and employment law for the state of: Idaho
I had worked for my employer for 2 years and was an excellent employee. I was made a manager and given a substantial raise within the first year. When I filled out my application, I listed my availability as 7:00 a.m. - 6:00 p.m. as I have a toddler who goes to daycare and there is no daycare in my area that opens before 6:00 a.m. They agreed to my schedule and all was fine until the corporate office declared a mandate that all people in my department begin work at 4:00 a.m. with no valid reason other than "because we say so". There was NO WAY I could leave for work at 3:30 a.m. as there was no daycare available and I would be in bed at night before my son.
I informed my boss that I was unable to work those hours and he said he'd "find someone else" and that he understood. I gave 2 weeks notice and never came in at 4 during my final 2 weeks. I filed for unemployment and was denied. I am currently appealing and have a hearing in less than 2 weeks.
It is my understanding that you can quit for good cause relating to the employment itself and not for personal reasons - so wouldn't THEIR change to my schedule be good cause. It was not a change on my end (i.e. my sitter quit or daycare facility closed down or changed their hours). There was no reason for them to change my hours based on my performance as I was an excellent employee and that was reflected in my raises as well as production and labor costs I was able to keep my department in. The employer admitted that the change was on their end and I did nothing wrong other than being unable to work those hours.
While I did quit, I believe I had no choice. I can't leave a toddler at home alone and they knew I couldn't work those hours so I was basically FORCED out of my job. They offered me no other positions or to work with my in any way - and admitted that to the unemployment office.
I have a family to support and am my wits end and need the unemployment benefits until I find other work. I need to know if I have a valid argument or what laws may apply to my situation so that I can bring them up during my hearing. I contacted an attorney, but he blew me off and told me my time would be better spent looking for work (which I am - but I'm in a smallish town and jobs in my profession aren't many).
Doesn't the fact that the company agreed to hire me based on my stated availability and work me ONLY during those hours for 2 years constitute an agreement of sorts? Wouldn't THEIR new corporate mandate with NO NOTICE TO ME (I was expected to start the new schedule the following day) give me good cause to quit?
Any information would be helpful! Thanks a bunch!
