My employer has transferred me to another location 50 kms away. Is this considered a constructive dismissal?

Yes, a move such as that is certainly significant enough to give rise to a constructive dismissal. This means that you are faced with the choice of either accepting the move or resigning and claiming your severance. Under no circumstances should you resign before we have had a chance to speak first. You can reach me at the number below.
