"Celiac disease can be considered a disability under the Americans with Disabilities Act (ADA) if it substantially limits one or more major life activities, including working. Employers are required to provide reasonable accommodations to qualified individuals with disabilities, which may include modifications to the work environment or adjustments in work schedules to accommodate the dietary needs of employees with celiac disease." So until you find a new job, I would think your current employer can and should and is legally required to accommodate you by not having you stock flour products.

Vitamin D deficiency may play a role in the severity of sciatica, with low levels potentially leading to increased pain sensitivity and inflammation. Adequate vitamin D levels may help reduce inflammation and improve nerve function, potentially easing pain associated with sciatica.  Also work on choosing food with low omega 6.  Omega 6 is inflammatory, omega 3 is healing.  The average American conusumes a diet with omega 6:3 ratio of 14:1.  Wheat flour ratio is 22:1. Iodine deficiency leads, among other things, weakened muscles.  Increasing your iodine intake to 600 mcg a day with Liquid Iodine will improve muscle tone.  Start with 1 drop a day (50 mcg).  The minimum intake RDA is 150 mcg.  The Tolerable safe upper limit is 1000 mcg.  Studies estimate the average daily intake of iodine per person in Japan to be more in the range of 1 to 5 mg/day.  In the US the population intake of Iodine has dropped 50% since 1970 and obesity has increased from 15% to 50%.   Are they connected?  Other common symptoms include fatigue, unexplained weight gain, constipation, dry skin, sensitivity to cold, and memory problems.
