I took a job at a retail store for Christmas (temp to hire). When I interviewed I was told some nights I would work late "Ok" and sometimes work early in the morning. My question was "How early and if I would be required to work very early after a late shift?" answer, "No earlier than 6 am and No" I said "Ok but I cannot work earlier because of commitments at home" I also told them of prior commitments and gave them a schedule of the dates which the reply was "this will not be a problem". I said Ok I will take the job.
Now I have been told I will work til 11pm Friday night and return to work at 4 am Saturday. I said "No, because I was not told I would have to work these hours and was not informed that this could happen."I had given them A list of hours available. Even though I am sure that they probably can.
Another incident is my being scheduled showing up for work and nobody shows up to unlock the store at the scheduled time (manager 1 hour late opening) then being told I had to stay an extra hour to finish my job. I had a dr's appointment and had to pick up my daughter after school. So i refused stating"..it was not my fault the store was not open for me to start my shift".They answered that since I was not working while I was in my car(duh) I should stay on the clock and make up the hour. No was my answer again I punched out and left at my scheduled time.
My question being, since there were conditions that were agreed upon before my employment am I right in refusing the hours scheduled?
This job is not my bread and butter. (I thank my lucky stars for that) it is just some Christmas money(I have a small gardening business) . So quitting is no big deal . But I wonder what they do to people who truly have to work there.
Thank you for your time.

Sorry for the edited post, one question was answered in my further reading in the forums

Conditions change. If you can't work the new hours, or overtime, because you have other committments, of course you can tell them that. However, should you be fired for not being able to "go with the flow", you would have no legal recourse.

Thank you, that is what I wanted to know.
I wasn't looking for a fight from them. If they feel they need to fire me so be it. And wouldn't be looking for legal recourse anyhow. That is more trouble than it is worth for this problem.
I just feel that if the hours I stated for my availability wasn't going to work for them, they should not have given me the position in the first place. It is a difficult position to fill.
I think I should put my 2 weeks in and they should find someone more suited to the hours they need. Up until this point I have gone with the flow but I can't compromise my family for a job that pays less than 8.00 dollars an hour.
Thank you again for the reply

You're not taking into consideration the fact that something may have changed at their end, which made it impossible for them to stick within the limitations they initially thought they would be able to hold to. Employee's circumstances can change: why not employers too?
