Health Benefits/Deduct from Pay

[ALCST5]

My daughter accepted a job in Sept 2005. Part of the job offer stated that she would be eligible for health benefits in 90 days. On Nov 30th the employer paid her health insurance premium for Jan 2006. My daughter resigned on Jan 3, 2006. She received a letter on Feb 4, 2006 from the employer that they deducted the insurance premium from her last pay and that she owes them around $50. Is this legal? My daughter sent them a letter in January stating that when she took the job that she assumed that the 90 days were 3 months. The employer responded that it was 90 working days not calendar days. The 90 days was not spelled out as 90 working days. Is there anywhere that I can get info on contract law and 90 days? Is what the employer did legal?

Of course it is. The fact that she ASSUMED it was 3 months does not obligate them to do it that way. Did she ask them?
