My wife, who has spent many years in her career of occupational therapy, tells me of the current ugly situation for newly qualified OT's having completed their four years university with their own financial difficulties and disillusionment and frustration at not working in their chosen field. Coming out with their own "licence "in their hand and working as care assistants. (no disrespect to care asistants)>
I know it's the smallest of consolations but our industry isn't unique in the current turmoil erupting across the marketplace.
I trust you find the job you're searching for. In the meantime, don't fall into the trap of letting your disappointment turn to bitterness. Good luck.
