About seven years ago, I had a lovely little job, which I enjoyed very much, and this included business health insurance as one of the perks of my salary. In fact, it was one of the biggest reasons why I accepted that position of employment in the first Place.
However, in the end the management of that company changed and they amended our contract of employment and removed the entitlement to this additional perk. Obviously I kicked up as huge a stink as I could - in fact, I pride myself on having secured a majority representation through a union, but we were still unsuccessful in having this perk reinstated.
We learnt quickly how employment law is often stacked in the favour of an employer and were all totally disgusted in the way our legal system had totally let us down. But as the country is now going through one of the depressed economic eras in something like 20,000 years, you can bet your bottom dollar that more and more employers are looking to this exact thing to save revenue.
Unfortunately, it would seem that if private health insurance is included in your salary at the start, you cannot guarantee that you will always keep hold of it. Many employers are slippery eels who will manage to find a way out of paying it, if they so wish.
Should this happen, let the employer get what they wish for: leave the company and find another as soon as you can who actually appreciates what you do and is willing to pay you accordingly. Leave the former employer to be left with second rate staff who will eventually make his business suffer - revenge is a dish best served cold!
