I been offered an interview for warehouse work closer to home but I'm happy in my cleaning job in a care home, so I wouldn't know what to do if I was offered a job. Also I haven't got my new job on my CV as it was sometime ago, do I tell them?
You've got a history of being dissatisfied with your jobs (or with employers being dissatisfied with your work). You've now found a job where you're happy (and, presumably, your employer is happy too).
I agree with all the others. Please stay where you are happy.
The grass sometimes seems greener somewhere else, but suppose the warehouse accepted you and then, later, laid you off. ? You would be left with no job again.
