A dental assistant is going to court because she claims she was let go from her job in an Ajax doctor's office because of her medical condition.

Veronica Jackson says the pain would flare up at the dental office where she worked:

In mid-November she says her family doctor told her to take a week off until she could see a specialist.

"That was the Thursday. I let [the office] know what was going on, [that I] needed a week off, And they're like, 'Okay we'll see what we can do try to cover you.' Then the Friday - next day - I got an email saying they had to let me go."

In the email the dental office wrote that it was giving Jackson one week's notice as required by Ontario employment standards.

The letter also stated, "It is unfortunate that your medical issues have gotten in the way of your duties as a dental assistant."

Jackson was shocked. "I was very upset," she said. "I really, really thought they'd understand."

The dental office declined to do an interview with us Thursday, but Dr. Daniel Bolshin told CBC News Jackson was fired because of her conduct at work and that she never showed any proof she had a medical condition.

Lawyers familiar with these types of disputes say the majority of discrimination cases that it sees are disability employment cases - and many deal with small employers.

"The law is sensitive to the fact that small employers may find it more difficult, but the small employer remains under responsibility to accommodate the needs of an employee who's having a health crisis or medical situation," said Katherine Laird of the Human Rights Legal Support Centre.

Jackson was recently diagnosed with fibromyalgia, a disorder that causes muscular pain.

She's suing the dental office because she feels she was treated unfairly.
