I recently signed a Employment offer letter which had included "Title, Salary, etc & Start Date". I was scheduled to start today, but yesterday evening I received an email informing me that my start date has pushed back 1 week (estimated).
Is this considered a breach in contract? I have other employment opportunities and was wondering if I decline offer due to starting date change was enough justification to bail out. This is a former employer and feel like I'm burning bridges.
Any input would be great. Thanks

Not considered a breach of contract, they did inform you properly and in good time.
